  1. Biographical narrative in relation to Great History : Les éblouissements by Pierre Mertens

    Directory of Open Access Journals (Sweden)

    Jerzy Lis

    2012-01-01

    Full Text Available Pierre Mertens’ novel Les éblouissements, published in 1987, is a fictionalised biography of a famous German poet Gottfried Benn, who made the biggest mistake of his life agreeing to support the National Socialist regime during several months. Mertens reconstructs the poet’s life trying to understand the reasons of his commitment, considered by the intellectuals of that time to be a betrayal. Mertens’ text is an illustration of the relationship between the individual and the historical past and, at the same time, an example of problemising the biographical factor in relation to Great History. Playing with the double signification of the word ‘éblouissement’, the novelist offers his own interpretation of the German poet’s double life.

    Francis Perrin had a brilliant and rapid career. He was a strict and honest man. He had a fast intelligence, a huge knowledge, he was faithful. Finally his courtesy and his generosity had made of him an outstanding and model personality very little known because of his extreme discretion. He lived his professional career (1920-1970) with passion. He thought that science might be one mankind heritage. He worked in CEA and played a crucial role in the CERN creation. He was an accomplished scientist since he tackled the mathematics, physics, and even chemistry scope. 52 refs

    2014-09-01

    Full Text Available Sisal (Agave sisalana Perrine is used for the extraction of fibers present in their leaves, being considered the main hard fiber produced in the world. However, a decline has been observed for this crop, due to a disease caused by the soil fungus Aspergillus niger. Biotechnology, particularly tissue culture techniques, represents a viable alternative for propagating this species. Among these techniques, the somatic embryogenesis can be pointed out. Thus, this study aimed to characterize the in vitro morphogenesis, during somatic embryogenesis, in A. sisalana Perrine. In all experiments, bulblets were used as explants and also ½ MS medium plus sucrose (30.0 g L-1, solidified with agar (7.0 g L-1 supplemented with different concentrations of auxin and cytokinin. The explants formed callus with compact and semi-compact aspects, pointing out the embryogenic cells converted into somatic embryos with the use of 2,4-D and BAP. The anatomic analyzes showed embryos in globular and torpedo stages and no connection with the mother callus.

  9. RIG-I-Like Receptor Signaling in Singleton-Merten Syndrome

    2017-09-01

    Full Text Available Singleton-Merten syndrome (SMS is an autosomal dominant, multi-system innate immune disorder characterized by early and severe aortic and valvular calcification, dental and skeletal abnormalities, psoriasis, glaucoma, and other varying clinical findings. Recently we identified a specific gain-of-function mutation in IFIH1, interferon induced with helicase C domain 1, segregated with this disease. SMS disease without hallmark dental anomalies, termed atypical SMS, has recently been reported caused by variants in DDX58, DEXD/H-box helicase 58. IFIH1 and DDX58 encode retinoic acid-inducible gene I (RIG-I-like receptors family members melanoma differentiation-associated gene 5 and RIG-I, respectively. These cytosolic pattern recognition receptors function in viral RNA detection initiating an innate immune response through independent pathways that promote type I and type III interferon expression and proinflammatory cytokines. In this review, we focus on SMS as an innate immune disorder summarizing clinical features, molecular aspects of the pathogenetic pathway and discussing underlying mechanisms of the disease.

    In Paris in 1894, two young physicists fall in love: Marie Sklodowska and Pierre Curie. They get married and make great contributions to science, research radioactivity and discover new chemical elements. The marriage of Marie and Pierre Curie is quite modern: They work together as equals, share their thoughts and pursue their plans together as partners. They share an absolute interest in science, a love of nature, and a sceptic attitude towards the sophisticated society of the Belle Epoque. They are together 24 hours a day with hardly ever any disagreement. Whenever one of them is ill - which is quite often because of the high level of radioactivity in their laboratory -, the other will nurse him or her. After only twelve years of mutual love, Pierre Curie dies. Marie raises their two daughters on her own and continues her research. In 1911, she will be the first scientist that ever gets a second Nobel Prize. (orig.) [German] Im Paris des Jahres 1894 verlieben sich zwei junge Physiker: Marie Sklodowska und Pierre Curie. Sie heiraten und leisten gemeinsam Grosses fuer die Wissenschaft, erforschen die Radioaktivitaet und entdecken neue chemische Elemente. Zusammen erhalten sie den Nobelpreis. Marie und Pierre Curie fuehren eine Ehe, die ihrer Zeit weit voraus ist: Sie arbeiten gleichberechtigt miteinander, teilen ihre Gedanken und verfolgen ihre Plaene gemeinsam. Beiden eigen ist die absolute wissenschaftliche Neugier, die Liebe zur Natur und die Skepsis gegenueber der mondaenen Gesellschaft der Belle Epoque. Fast jeden Tag sind sie rund um die Uhr zusammen, dabei gibt es selten Spannungen. Wenn einer von beiden gesundheitliche Probleme hat - und das haben sie wegen der radioaktiven Belastung im Labor oft - ist der andere fuer ihn da und pflegt ihn. Nach nur zwoelf gemeinsamen Jahren der Liebe und Arbeit stirbt Pierre Curie. Marie zieht ihre beiden Toechter alleine gross und fuehrt die Forschungen weiter. 1911 erhaelt sie als erster Mensch zum zweiten Mal den

  13. The Pierre Auger project

    1996-01-01

    The Pierre Auger project is a broadly based international effort to make a detailed study of cosmic rays at the highest energies. Two air shower detectors are proposed, one to be placed in the Northern Hemisphere and one in the Southern Hemisphere. Each installation will consist of an array of 1600 particle detectors spread over 3000 km 2 with a solid angle acceptance of 2 sr for cosmic ray air showers. Eah installation will also have an atmospheric fluorescence detector viewing the volume above the surface array. These two air shower detector techniques working together form a powerful instrument for the proposed research. The objectives of the Pierre Auger project are to measure the arrival direction, energy, and mass composition of 60 events per year above an energy of 10 20 eV and 6000 events per year above 10 19 eV. A collaboration is now being formed with the goal of having the Pierre Auger observatory in operation by 2001

How empty this sounds when you knew Pierre. “He wrote great software!”; “Look at his project, building 774, isn't it amazing?”; “We had lots of good laughs together!”. All of this is true, but none of it really does him justice. Pierre was a special person who had the capacity to make you feel good whenever he was around.

  20. Evaluation of excavation experience: Pierre shale. Final report

    Abel, J.F. Jr.; Gentry, D.W.

    1975-01-01

    Pierre shale and its stratigraphic equivalents represent a potentially favorable geologic environment for underground storage of hazardous waste products. These rock formations cover great areal and vertical extents, and represent some of the least permeable rock formations within the continental United States. There are, however, several engineering problems associated with constructing underground openings in Pierre shale. This formation is relatively weak and tends to deteriorate rather rapidly if not protected from the mine environment. It will be necessary to place all underground openings below the surficially weathered upper 50 to 70 feet of Pierre shale which contains groundwater moving on fracture permeability. The optimum site for disposal of hazardous waste in Pierre shale, or its stratigraphic equivalents, would be a seismically stable platform bounded on all sides by faults. The optimum size of individual openings would be the minimum necessary for access, storage, and retrieval of waste components. Underground excavations in Pierre shale must be made with care, must be of limited dimensions, must be widely spaced, must be protected from prolonged contact with the mine environment, must be supported immediately after excavation, and must be sited to avoid areas of faulting and(or) intense jointing. Underground openings constructed with boring machines and supported with wet shotcrete are recommended

    Many operations of aesthetic surgery were described between 1920 and 1930. Several French surgeons are recognized as pioneers of the speciality. Pierre Mornard (1883-1929) published numerous articles of plastic and aesthetic surgery between 1925 and 1929 the date of his death. The articles were illustrated with drawings of surgery he had practiced. He described in 1929 the first abdominoplasty with umbilical transposition. Pierre Mornard can be considered a pioneer of aesthetic surgery. Copyright © 2016. Published by Elsevier Masson SAS.

    Dark and light terrain materials in the Perrine and Nun Sulci quadrangles are divided into nine map units, four dark, and five light. These are placed in time-stratigraphic sequence primarily by means of embayment and cross-cutting relationships. Dark terrain is generally more heavily cratered and thus older that light terrain but, at least in these quadrangles, crater densities are not reliable indicators of relative ages among the four dark material units. The four mapped material units within dark terrain are: cratered dark materials (dc), grooved dark materials (dg), transitional dark materials (di), and dark materials, undivided (d). The five mapped units within light terrain are: intermediate light materials (li), grooved light materials (lg), irregularly grooved light materials (lgl), smooth light materials (ls), and light materials, undivided.

    2011-01-01

    Pierre-Joseph Proudhon’s ideas on credit and money have been considered to be not very relevant and above all unrealistic. However, they have known an uncommon posterity. They influenced Silvio Gesell who is John Maynard Keynes’s reference. This article analyses Pierre-Joseph Proudhon’s exchange bank plan. We show that Pierre- Joseph Proudhon’s ideas on credit and money are opened to criticism but require a reexamination because we can draw many lessons from them.

    Full Text Available Nato in Algeria, in una tradizione musulmana, da adolescente Pierre Rabhi si converte al Cristianesimo e a vent’anni approda a Parigi per lavorare come operaio specializzato. Dopo tre anni di una vita “in scatola” abbandona la capitale per installarsi nel Sud Est della Francia. Diventato operaio agricolo, si oppone però ben presto alla logica di produttività intensiva e innaturale dell’agricoltura industriale. Da autodidatta studia l’agricoltura biodinamica e biologica applicandone con successo i metodi fino a creare quella che lui ama definire un’oasi di vita. Da anni ormai Pierre Rabhi è incessantemente impegnato a promuovere un nuovo paradigma di vita basato sul rispetto dell'uomo e della terra.

    The mass composition of ultra-high energy cosmic rays is a critical issue to understand their origin and nature. The Pierre Auger Observatory is a hybrid instrument which provides a powerful environment for the determination of the primary mass. The Surface Detector of the Pierre Auger Observatory alone allows the study of several shower parameters with high discriminating power between primary elements. Novel analysis techniques using different features of signals in the Cherenkov stations are discussed. These are the signal risetime, the azimuthal time asymmetry and the muon density of the showers.

  17. Measurement of in-situ hydraulic conductivity in the Cretaceous Pierre Shale

    International Nuclear Information System (INIS)

    Neuzil, C.E.; Bredehoeft, J.D.

    1981-01-01

    A recent study of the hydrology of the Cretaceous Pierre Shale utilized three techniques for measuring the hydraulic conductivity of tight materials. Regional hydraulic conductivity was obtained from a hydrodynamic model analysis of the aquifer-aquitard system which includes the Pierre Shale. Laboratory values were obtained from consolidation tests on core samples. In-situ values of hydraulic conductivity were obtained by using a borehole slug test designed specifically for tight formations. The test is conducted by isolating a portion of the borehole with one or two packers, abruptly pressurizing the shut-in portion, and recording the pressure decay with time. The test utilizes the analytical solution for pressure decay as water flows into the surrounding formation. Consistent results were obtained using the test on three successively smaller portions of a borehole in the Pierre Shale. The in-situ tests and laboratory tests yielded comparable values; the regional hydraulic conductivity was two to three orders of magnitude larger. This suggests that the lower values represent intergranular hydraulic conductivity of the intact shale and the regional values represent secondary permeability due to fractures. Calculations based on fracture flow theory demonstrate that small fractures could account for the observed differences

    We describe a new method of identifying night-time clouds over the Pierre Auger Observatory using infrared data from the Imager instruments on the GOES-12 and GOES-13 satellites. We compare cloud identifications resulting from our method to those obtained by the Central Laser Facility of the Auger Observatory. Using our new method we can now develop cloud probability maps for the 3000 km^2 of the Pierre Auger Observatory twice per hour with a spatial resolution of ~2.4 km by ~5.5 km. Our method could also be applied to monitor cloud cover for other ground-based observatories and for space-based observatories.

    Pierre Robin sequence (formerly a syndrome) is named after the French stomatologist who, in 1923 and 1934, described the problems associated with micrognathia in newborn. It comprises mandibular micrognathia, U-shaped cleft palate, and glossoptosis. The typical symptoms are hypoxaemia, noisy breathing, snoring, stridor, cyanosis, bradycardia, feeding difficulties, and failure to thrive. Distraction osteogenesis has recently been considered as a surgical option for early intervention to lengthen the mandible and relieve respiratory problems. Piezosurgery offers a modality to make precise bone cuts preserving vital structures, minimizing the invasiveness of the surgical procedure, and offering bloodless field. We present case of 1-year-old male malnourished child with Pierre Robin sequence and tracheostomy in situ since day 11 of his birth. The staged treatment plan involving mandibular lengthening in which mandibular osteotomies were performed with the piezoelectric scalpel followed by decannulation of tracheostomy, which has been described in detail in this article.

    2013-01-01

    Full Text Available The observation of ultrahigh energy neutrinos (UHEνs has become a priority in experimental astroparticle physics. UHEνs can be detected with a variety of techniques. In particular, neutrinos can interact in the atmosphere (downward-going ν or in the Earth crust (Earth-skimming ν, producing air showers that can be observed with arrays of detectors at the ground. With the surface detector array of the Pierre Auger Observatory we can detect these types of cascades. The distinguishing signature for neutrino events is the presence of very inclined showers produced close to the ground (i.e., after having traversed a large amount of atmosphere. In this work we review the procedure and criteria established to search for UHEνs in the data collected with the ground array of the Pierre Auger Observatory. This includes Earth-skimming as well as downward-going neutrinos. No neutrino candidates have been found, which allows us to place competitive limits to the diffuse flux of UHEνs in the EeV range and above.

    Full Text Available In this paper the invertebrate fauna occurring on Scoglio Faraglione, a tiny Aeolian island (AeolianArchipelago, NE Sicily inhabited by a population of the critically endangered lacertid lizard Podarcis raffonei(Mertens, 1952, was censused at different seasons and the resulting data were then compared with dataobtained analysing prey composition and prey abundance in the diet of the lizards occurring on the same islet.The diet of Podarcis raffonei was mainly based on insects and other arthropods. The results indicate that dietcomposition is not directly influenced by prey availability and temporal prey abundance, and that there isstrong evidence indicating selective predation. Lizards prey upon a number of arthropod categories fewer thanthat recorded in field. Some invertebrate taxa (e.g. Diptera and Gastropoda are really less attractive for lizardsand are rarely preyed or not preyed at all despite their spatial and/or temporal abundance. This suggests thatPodarcis raffonei is able to operate a hierarchical choice within the range of prey items constituting its preyspectrum, probably through the ability to discriminate between prey chemicals or visually oriented predation.

    We describe the method devised to reconstruct inclined cosmic-ray air showers with zenith angles greater than 60° detected with the surface array of the Pierre Auger Observatory. The measured signals at the ground level are fitted to muon density distributions predicted with atmospheric cascade models to obtain the relative shower size as an overall normalization parameter. The method is evaluated using simulated showers to test its performance. The energy of the cosmic rays is calibrated using a sub-sample of events reconstructed with both the fluorescence and surface array techniques. The reconstruction method described here provides the basis of complementary analyses including an independent measurement of the energy spectrum of ultra-high energy cosmic rays using very inclined events collected by the Pierre Auger Observatory.

    Introduction: Pierre Robin syndrome is a congenital condition of facial abnormalities in humans. The three main features are: cleft palate, retrognathia and glossoptosis. Rarely heart tumors are associated with syndromes, mostly are isolated. Case report: In this presentation we describe a 3-weeks-old girl with Pierre-Robin syndrome and giant left ventricle tumor, diagnosed initially by transthoracic echocardiography. The purpose of this report is to review the literature on the fetuses and neonates with cardiac tumors in an attempt to determine the various ways which cardiac tumors differ clinically and morphologically in this age group.

    Endotracheal intubation in infants with the Pierre Robin syndrome may sometimes be impossible to accomplish by conventional means. To aid difficult tracheal intubation many different techniques have been described. We present a case, in which we successfully intubated a small-for-date newborn boy...... with the Pierre Robin syndrome by using a modified laryngeal mask airway (no. 1) as a guide for the endotracheal tube. The technique is easy to perform, less traumatic and less time-consuming than multiple attempts at laryngoscopy or blind tracheal intubation....

  15. Pierre Schaeffer and his theory of listening

    2011-12-01

    Full Text Available This work presents a diachronic study of Pierre Schaeffer’s texts from 1942, 1950 and 1966. It shows the mechanics of his theory of listening, following in the author’s footsteps to highlight the creation of concepts by accumulation, a procedure he takes to extremes in the notion of quatre fonctions de l’écoute. One concludes that écoute réduite is not a compositional aesthetics but rather a poetics of aural perception.

    Utilizing concepts from Pierre Bourdieu I argue that the implementation of financial literacy education in Ontario public schools will, if uncontested, support a neoliberal consumer habitus (subjectivity) at the expense of the critical citizen. This internalization of the neoliberal ethos assists state efforts to shift responsibility for…

    While the work to make data acquisition fully automatic continues, both the Fluorescence Detectors and the Surface Detectors of the Pierre Auger Observatory need some kind of attention from the local staff. In the first case, the telescopes are operated and monitored during the moonless periods. The ground array only needs monitoring, but the larger number of stations implies more variables to consider. AugerAccess (a high speed internet connection) will give the possibility of operating and monitoring the observatory from any place in the world. This arises questions about secure access, better control software and alarms. Solutions are already being tested and improved.

    The Pierre Auger observatory is a hybrid air shower experiment which uses multiple detection techniques to investigate the origin, spectrum, and composition of ultrahigh energy cosmic rays. We present recent results on these topics and discuss their implications to the understanding the origin of the most energetic particles in nature as well as for physics beyond the Standard Model, such as violation of Lorentz invariance and 'top-down' models of cosmic ray production. Future plans, including enhancements underway at the southern site in Argentina will be presented. (author)

    2010-04-01

    After difficult beginnings as a farm boy in Brittany, and then as a dish-washer at a chemist's in Paris, Pierre Famel (1855-1934) obtained his grammar certificate in 1879 and then his 2nd class chemist diploma from the Ecole de pharmacie de Paris in 1885. He was employed by the Laboratoire municipal de la Ville de Paris as an expert chemist. In 1886 he set himself up in a pharmacy at 86, rue de la Réunion, in Paris, known as the Pharmacie Famel. In 1912 he created the Laboratoires Famel for the manufacture of pharmaceutical products with sales representation in several European, North and South American as well as Canadian cities. He marketed among other things Famel Syrup, Famel suppositories, Langlebert glycophosphated wine, Sulfogène Famel and Optraex. The Famel firm obtained several awards at Exhibitions in France and elsewhere. On the death of Pierre Famel, the dispensary was sold, while his daughter and his granddaughter formed a partnership to manage the Laboratories. They still exist today as a finance company, the main activity of which is the management of its heritage. Pierre Famel was a foreign trade adviser, a vice-president of the Franco-Czechoslovakian and Franco-Iranian Chambers of Commerce. He created a prize for commercial attachés, as well as annual fellowships for students from foreign medical faculties. He was a sponsor of several youth clubs and charitable organizations, as well as a member of several Breton associations. He was the President of the Society of the Friends of the Pharmacology Faculty in Paris as well as the founder of the Museum devoted to Henri Moissan, the first French winner of the Nobel Price in Chemistry, who was for him a guide and a teacher in his early life and studies. He was a Commander of the Legion of Honour (1925) and was awarded the Gold Medal of foreign trade (1933). Also briefly mentioned are his wife, Marie Famel, an enamel painter, his daughter Yvonne Famel, and his son-in-law, Sylvain Rosengart, with whom

    Full Text Available O presente texto procura discutir o legado deixado pelo sociólogo francês Pierre Bourdieu. Dez anos após sua morte, tem-se discutido, em nível internacional, a relevância deste autor, um dos mais influentes e citados teóricos do mundo. Para a identificação desta influência no Brasil, mais especificamente no campo educacional brasileiro, pesquisou-se nas teses e dissertações encontradas no banco de dados da CAPES, que referenciavam Bourdieu, de que forma estaria se dando a apropriação de seu quadro teórico de análise para construção de conhecimento no referido campo. Concluiu-se que o número de produções defendidas nos Programas de Pós-Graduação em Educação no Brasil, de 1965 a 2010, cresce de forma exponencial, demonstrando o quão profícua a utilização da teoria sociológica de Bourdieu tem se mostrado para explicar a realidade da Educação no Brasil na contemporaneidade. Encerra-se o artigo com uma reflexão sobre a consideração do status de Bourdieu como um clássico da Sociologia que, paradoxalmente, se mostra mais atual e vivo do que qualquer outro autor quando se trata de aplicar seu princípio maior, a saber, analisar o mundo social e suas lógicas, desvelando as formas de dominação e as misérias sociais.This paper's intent is to discuss the legacy left by the French sociologist Pierre Bourdieu. Ten years after his death, it has been discussed at an international level the relevance of this author, one of the most cited and influential theorists in the world. To identify such influence in Brazil, more specifically in the Brazilian educational field, we investigated theses and dissertations found in CAPES database, which referenced Bourdieu, to identify how those works use his theoretical framework of analysis for construction of knowledge in that field. It was concluded that the number of productions held in post-graduate programs in education in Brazil, from 1965 to 2010, grows exponentially

    Science.gov (United States)

    2010-11-01

    This issue is devoted to our colleague and friend Pierre Duclos who passed away suddenly and prematurely in Prague on 12 January this year. We want to honour his memory in the way he would have liked, by collecting fresh and original work from his area of interest. Pierre Duclos was born on 8 January 1948 in Paris. He started as an engineering student but also attended graduate courses at the Centre de Physique Théorique (CPT) in Marseille, which inspired him to change his path and pursue the professional career of a researcher. He joined the Mathematical Physics team at CPT and obtained a position at the University of Toulon, where he later became a full professor. He was never solitary; always being full of energy and a smart and sociable person, he started and maintained many international collaborations and organized numerous conferences and seminars. In the early eighties he had strong ties with the Free and Technical Universities of Berlin. From the beginning of the nineties, he collaborated with coleagues in Prague, Bucharest, Santiago de Chile, and more recently also in Aalborg and Dublin. His scientific interests were wide, with a focus on mathematical methods of quantum theory. He made important contributions to our understanding of multiple-well Schrödinger operators, geometrically-induced properties of quantum waveguides, spectra of Wannier-Stark systems, dynamics with time-periodic perturbations, and transport in mesoscopic systems, to name his most significant results. We choose for this issue the title `Spectral and transport properties of quantum systems' which cover the subjects of most papers to which his colleagues, and often coauthors, contributed. We have also included a few other papers with topics related to Pierre's work. We are glad we were able to gather a numerous collection of papers which in our view represent interesting new developments. A few of them are works which bear Pierre's signature and have been completed by his

    Full Text Available Professor Elizabeth Adams St. Pierre’s work focuses on critical and poststructural theories of language and the subject and what she has called post qualitative inquiry or post inquiry. She asks what might come after conventional humanist qualitative research methodology. She’s especially interested in the new empiricisms/new materialisms as well as new research practices enabled by the ontological turn. During St. Pierre's visit to the Finnish Educational Research Association (FERA Conference in Oulu in November 2014, we had the opportunity to talk with her about post qualitative research around some questions we had sent her beforehand. We then transcribed, edited, and translated the interview, and published it in the Finnish journal Kasvatus (Education in spring 2015. In this interview St. Pierre talks in the US context, where qualitative methodology is turning—or being pushed to turn—back to positivism with normalized and formalized practices, St. Pierre encourages researchers to constantly question the prevailing truths and the traditions they have learnt too well.

  10. Pierre Bayard's Wormholes

    2011-06-01

    Full Text Available The recent work of Pierre Bayard is trenchant, original, and deeply engaging. From Qui a tué Roger Ackroyd? (1998 Who Killed Roger Ackroyd? (2001 onward, Bayard's books have piqued the interest of readers well beyond the limited circle of those who habitually consume French criticism and literary theory, and have served thus to expand the horizon of possibility of critical writing in significant ways. Bayard writes in a conditional, hypothetical mode, rather than a declarative one, keenly aware of how very mobile literary objects are. Bayard is not afraid to take risks, and he searches for new forms through a process of bold experimentation. He seeks moreover to enlist his reader in that quest, proposing a contract to him or her, one whose principal clauses are articulative and ludic. Fictional worlds are incomplete, he argues, and we readers must intervene in them in order to palliate that incompletion, through our interpretations. We accede to fictional worlds through wormholes, passages joining places that are thought to be unconnected. With this interventionist model, Bayard encourages us to reconsider the way that we read fiction, and also the way that we read critical writing.

    A 3-month-old male infant with clinical and radiological features of Kniest disease is reported. Additional findings were severe Pierre Robin syndrome and external hydrocephalus. The patient was retarded in mental and motor development. He died at 4 months of age from the complications of tracheostomy. The parents were both normal clinically and radiologically, thus the disease in the child was presumably due to a new mutation. The reported familial cases of Kniest disease suggest autosomal dominant inheritance. The differential diagnosis is discussed in detail. (orig.)

    Full Text Available The greening of Christianity: Charles Darwin, Pierre Teilhard de Chardin and Lloyd Geering. Since the time of Charles Darwin, evolutionary biology challenged the metanarrative of Christianity which can be summarised as Fall-Redemption-Judgement. Pierre Teilhard de Chardin tried to circumvent these challenges by integrating the traditional Christian doctrines with evolutionary biology. However, he did not succeed since the Catholic Church, time and again, vetoed his theological publications. A number of Protestant theologians promoted his views but even they could not convince ordinary Christians to accept his views. These were too esoteric for Christians. Most of them were convinced that the acceptance of the theory of evolution will eventually undermine their faith. In recent years Lloyd Geering argued a case for the creation of a new narrative in which the Big Bang and the theory of evolution do play a role. He calls it the ‘Greening of Christianity’. This article discusses the metanarrative of Christianity and the challenges the theory of evolution presents before it assesses the views of Pierre Teilhard de Chardin and Lloyd Geering.

    The Pierre Auger Observatory explores the potential of radio-detection techniques to measure extensive air showers (EAS) induced by ultra-high energy cosmic rays. To study in detail the mechanisms responsible for radio emission in the MHz range, the Auger Engineering Radio Array has been installed at the Observatory. Presently consisting of 24 radio-detection stations, this number will grow to 150 units covering an area of almost 20 km 2 . Novel detection techniques based on the GHz emission from the EAS are currently being studied. AMBER (Air-shower Microwave Bremsstrahlung Experimental Radiometer) and MIDAS (Microwave Detection of Air Showers) are prototypes for a large imaging dish antenna. In EASIER (Extensive Air Shower Identification using Electron Radiometer), the microwave emission is detected by antenna horns located on each surface detector. MIDAS is a self-triggering system while AMBER and EASIER use the trigger from the Auger detectors to record the emission. The status of these radio-detection R and D efforts at the Pierre Auger Observatory will be reported

La cuestión educativa, pese a lo que pudiera considerarse, se hace extensiva a toda la sociedad en su conjunto, creando para ellos universidades populares, donde todas las capas sociales podían acceder al hecho cultural. Además de reivindicar el valor educativo del discurso de Coubertin, los autores plantean una reflexión del discurso olímpico en nuestros días, señalando una lectura educativa con respecto al extendido deporte espectáculo.Changes that have happened in the 19th century regarding education and politics resulted in a closer approach of Pierre de Coubertin to Olympic games as way «f cultural development. Pierre de Coubertin, founded the Modern Olympic games at the end of 1 9 century. At that time there were pedagogical reflections about sports. Coubertin is, as well, an excellent sport theoretician. In our country, there is a lack of studies about this fact. The educational issue extends to the society as a whole, creating courses where any social stratum could study. Apart from claiming, the educational value of Coubertain's theory, authors bring up reflections about the Olympic theory, showing an educational view of sport entertainment.

    The Pierre Auger Observatory is the world's largest experiment detecting extensive air showers initiated by cosmic rays at the highest energies. An area of 3000 km{sup 2} is instrumented by 1660 water Cherenkov detector stations, and 27 fluorescence telescopes overlook the atmosphere above the surface detector array. A hybrid detection principle is achieved by utilizing information of both detectors. A major upgrade of the experiment (AugerPrime) has been decided adding a third detector type, scintillator detector stations located on the water Cherenkov tanks. Thereby, the composition sensitivity of the Pierre Auger Observatory is extended by an improved determination of the muonic shower component. Additionally, underground muon detectors (AMIGA) are deployed. The experiment has been further extended by antennas measuring the emission of radio signals from air showers (AERA). An overview about recent results and the current status of the experiment are given in this talk. Highlights are updated results, e.g. on the energy spectrum, chemical composition or proton-air cross section.

    Full Text Available Se realizó un estudio prospectivo en 21 mujeres que presentaron incontinencia urinaria de esfuerzo, las cuales recibieron tratamiento quirúrgico por la técnica de Perrin modificada, en el Hospital General Docente "Guillermo Domínguez", del municipio Puerto Padre, en los años 1990 y 1991. Estas pacientes se siguieron después de operadas por espacio de 1 año, para evaluar los resultados mediatos obtenidos al aplicar esta técnica. Como principales resultados y conclusiones se expresan: la incontinencia urinaria de esfuerzo fue más frecuente después de la cuarta década de la vida, estuvo relacionada con la multiparidad y con el tipo de parto transpelviano; se encontró asociada con diversos grados de relajación pelviana, y resultaron los ligeros y medianos esfuerzos los que con mayor frecuencia la provocaron. Las pruebas de esfuerzo presentaron un alto grado de positividad. Técnicas quirúrgicas fallidas por vía vaginal, se recogieron como un antecedente importante. La retención urinaria fue la complicación posoperatoria más frecuente. El 95 % de los resultados mediatos alcanzados se evaluaron de satisfactorios

    Full Text Available In this article we will discuss measurements of the longitudinal development of air showers at the Pierre Auger Observatory. The longitudinal development of the electromagnetic component can be directly observed by the fluorescence telescopes of the Auger Observatory and we will present the results on the evolution of the average shower maximum and its fluctuations as a function of energy. Moreover, two observables from the surface detector, the asymmetry of the rise time of the station signals and the muon production depth, will be discussed and the measurements will be compared to predictions from air shower simulations for different primary particle types.

    Can we better understand Pierre Bourdieu's sociology by appealing to the intellectual references he made use of in his works? Not really, because confronting Bourdieu with the classical sources he relies on, as Marx, Weber or Bachelard, the reader can note a rather lax exercise of the concepts he is borrowing and he is making his. Or, this insight in Bourdieu's work takes the opposite way, as it tries to analytically read Bourdieu intellectual project on building sociology as science by start...

    Plastic scintillator-based detectors are simple and yet powerful instruments, commonly used in particle physics experiments. These detectors are also planned to be installed at the Pierre Auger Observatory as part of the upgrade called AugerPrime. Here, a single detector module will consist of several large-sized scintillator bars. Embedded wavelength shifting fibres read out the scintillation light and are coupled to a single photo-sensitive device. We investigate the application of silicon photomultipliers (SiPMs) in this scope, which benefits from high photon detection efficiency and stability. We show the performance of a SiPM-based prototype device installed in the 2 m{sup 2} detector ASCII - an early prototype of the scintillating detector planned for AugerPrime. We focus on the electronics, the optical coupling and the in situ calibration. As ASCII has been operating with SiPMs for several months now, we also highlight first high-energy events seen in coincidence with the Surface Detector of the Pierre Auger Observatory.

    2014-12-01

    The Pierre Auger Observatory detects the atmospheric showers induced by cosmic rays of ultra-high energy (UHE). It is the first one to use the hybrid technique. A set of telescopes observes the fluorescence of the nitrogen molecules on clear moonless nights, giving access to the longitudinal profile of the shower. These telescopes surround a giant array of 1600 water Cherenkov tanks (covering more than 3000 km{sup 2}), which works continuously and samples the particles reaching the ground (mainly muons, photons and electrons/positrons); the light produced within the water is recorded into FADC (Fast Analog to Digital Convertes) traces. A subsample of hybrid events provides a cross calibration of the two components. We describe the structure of the Cherenkov detectors, their sensitivity to different particles and the information they can give on the direction of origin, the energy and the nature of the primary UHE object; we discuss also their discrimination power for rare events (UHE photons or neutrinos). To cope with the variability of weather conditions and the limitations of the communication system, the procedures for trigger and real time calibration have been shared between local processors and a central acquisition system. The overall system has been working almost continuously for 10 years, while being progressively completed and increased by the creation of a dense “infill” subarray. - Highlights: • The water Cherenkov technique is used in the Surface Detector of the Pierre Auger Observatory. • Cross-calibrated with the Fluorescence Detector, it provides a measurement of the primary energy. • The spectrum of the UHE cosmic rays exhibits clearly an “ankle” and a cutoff. • The muon observed muon content of the atmospheric showers is larger than expected from the models. • Stringent limits on the flux of UHE neutrinos and photons are obtained.

    Full Text Available The Pierre Auger Observatory, located in Argentina, provides an unprecedented integrated aperture in the search for primary photons with energy above 1017 eV over a large portion of the southern sky. Such photons can be detected in principle via the air showers they initiate at such energies, using the complement of Auger Observatory detectors. We discuss the results obtained in diffuse and directional searches for primary photons in the EeV energy range.

    Full Text Available The present study evaluated the anti-inflammatory and analgesic properties of Agave sisalana Perrine in classic models of inflammation and pain. The hexanic fraction of A. sisalana (HFAS was obtained by acid hydrolysis followed by hexanic reflux. Anti-inflammatory properties were examined in three acute mouse models (xylene ear oedema, hind paw oedema and pleurisy and a chronic mouse model (granuloma cotton pellet. The antinociceptive potential was evaluated in chemical (acetic-acid and thermal (tail-flick and hot-plate test models of pain. When given orally, HFAS (5, 10, 25 and 50 mg/kg reduced ear oedema (p < 0.0001; 52%, 71%, 62% and 42%, respectively. HFAS also reduced hind paw oedema at doses of 10 mg/kg and 25 mg/kg (p < 0.05; 42% and 58%, respectively and pleurisy at doses of 10 mg/kg and 25 mg/kg (41% and 50%, respectively. In a chronic model, HFAS reduced inflammation by 46% and 58% at doses of 10 mg/kg and 25 mg/kg, respectively. Moreover, this fraction showed analgesic properties against the abdominal writhing in an acetic acid model (at doses of 5-25 mg/kg with inhibitory rates of 24%, 54% and 48%. The HFAS also showed an increased latency time in the hot-plate (23% and 28% and tail-flick tests (61% and 66% for the 25 mg/kg and 50 mg/kg doses, respectively. These results suggest that HFAS has anti-inflammatory and analgesic properties.

    Full Text Available The following article offers an interpretation of Pierre Bayard’s anachronistic criticism in order to look into the relationship between time and literature, and to problematize the way in which we understand literary history. To that end, we will analyze the deconstructionist strategies deployed by the French critic (such as irony and paradox which lead to notions such as anticipatory plagiarism. This will drive us to a comparison with other manners of thinking literary history, including those we find in Harold Bloom’s and Hans-Robert Jauss’s works. Finally, this article will try to lay the foundation of the hypothesis according to which the questioning of literary history leads to a reading theory. Cet article offre une interprétation de la critique anachronique de Pierre Bayard afin d’enquêter la relation entre le temps et la littérature et de problématiser la manière dont on comprend l’histoire littéraire. Pour ce faire, nous analyserons les stratégies déconstructionnistes déployées par le critique français (comme l’ironie et le paradoxe qui mènent vers des notions telles que le plagiat par anticipation. Cela nous conduira à une comparaison entre les façons de penser l’histoire littéraire chez des auteurs comme Harold Bloom et Hans-Robert Jauss. Finalement, l’article cherchera à poser les bases de l’hypothèse selon laquelle la problématisation de l’histoire littéraire conduit à une théorie de la lecture.

    Full Text Available Através de uma apresentação, em ordem cronológica, da obra de Pierre Bourdieu, tentou-se extrair as idéias, os elementos teóricos e os conceitos elaborados por ele. Começando com um trabalho de campo na Argélia, ele desenvolveu pouco a pouco um sistema de explicação sociológica da dominação social. A escola, a cultura, a economia foram, entre outros, estudadas aplicando conceitos novos na sociologia, tais como habitus, violência simbólica ou campo social. Propondo uma nova leitura das relações sociais, Bourdieu criou um modo de pensar suscitando criticas severas, mas também uma obra profícua utilizada nos mais variados setores sociais.Through a chronological presentation of Bourdieu's work, we tried to extract his ideas and the theoretical elements and concepts he formulated. Beginning his fieldwork in Algeria, he gradually developed an explanatory system of social domination. School, culture, economy have been studied, among others, under the application of such new sociological concepts as habitus, symbolical violence or social field. Proposing a new reading of the social relationships, Bourdieu created a way of thinking used in various social sectors that aroused as many criticisms as fruitful researches.

    Our colleagues at the Sociedade Brasileira de Medicina Tropical have been informed of the demise of Professor Pierre Ambroise-Thomas (1937-2014). However, considering that the tribute we paid to him in 2015 - at the 20th anniversary of the Seminário Laveran & Deane sobre Malária - is equally true today, it is worth sharing it with the readers of the RSBMT, in recognition of his many virtues. Pierre Ambroise-Thomas (MD in 1963 and DSc in 1969) was Honorary Professor of Parasitology and Tropical Medicine at the Faculté de Médecine de Grenoble (France), Honorary President of the Académie Nationale de Médecine, member of the Académie Nationale de Pharmacie and Officier dans l'Ordre de La Légion d'Honneur. In addition to his important contributions to tropical medicine and parasitology, working in France during his long and productive career (50 years and 300 publications), Ambroise-Thomas became an admirer and supporter of Brazilian activities related to research, teaching and information in Tropical Medicine.

    Full Text Available A book published in 2012 included the publication of the lecture course on the State delivered by Pierre Bourdieu at the Collège de France. The course was given at a time when Bourdieu’s work had reached full maturity, and it completed, at the most generic level of significance —in the “geometral of all perspectives”— the analytical potential opened up by the main categories he used to approach the social world: habitus, field and, above all, capital or symbolic power, the true core of uncontested legitimacy and of the omnipresent domination that the state has acquired in the contemporary world.

    Bair, W.C.; Simpson, S.G.; Windingstad, R.M.

    1988-01-01

    Aspergillosis was diagnosed at the cause of death of 158 mallards (Anas platyrhynchos) in January and February 1985 and 11 mallards in December 1985 near Pierre, SD. Isolation of Aspergillus fumigatus from carcass tissues confirmed the diagnosis. The sex ratio of mallards dead from aspergillosis in January and February 1985 was significantly different from the sex ratio in the local population at that time. The source of the fungus was not determined, but severe weather caused physiologically stressed mallards to feeds on corn stored in open piles on the ground, a likely source of the Aspergillus fungus.

    The Pierre Auger Observatory has begun a major Upgrade of its already impressive capabilities, with an emphasis on improved mass composition determination using the surface detectors of the Observatory. Known as AugerPrime, the upgrade will include new 4 m2 plastic scintillator detectors on top of all 1660 water-Cherenkov detectors, updated and more flexible surface detector electronics, a large array of buried muon detectors, and an extended duty cycle for operations of the fluorescence detectors. This Preliminary Design Report was produced by the Collaboration in April 2015 as an internal document and information for funding agencies. It outlines the scientific and technical case for AugerPrime. We now release it to the public via the arXiv server. We invite you to review the large number of fundamental results already achieved by the Observatory and our plans for the future.

    The Pierre Auger observatory's main aim is to observe the ultra-energetic cosmic ray spectrum with high statistics. Indeed, the spectrum around 10{sup 20} eV is so far only poorly known, due to low statistics and the expected GZK (Gneisen-Zatsepin-Kuzmin) cut-off is for the time being not clearly observed. The first part will deal with propagation of charged (protons and nuclei) ultra-energetic cosmic rays in the extragalactic medium. We will investigate the influence of physical parameters, such as the composition of cosmic ray fluxes, on the highest energy spectrum shape. The influence of the turbulent extragalactic magnetic fields on the spectrum of the clusters will also be studied. We will also investigate the possibility to observe gamma ray bursts with the Pierre Auger Observatory by using the single particle technique. We will show how galactic gamma ray bursts could become a persistent and quasi-isotropic source due to the 'Compton trail' induced by Compton scattering of the primary photon beam in the interstellar medium. In the section devoted to simulations, we will develop methods to reconstruct air showers and identify primary cosmic rays. We will also study the aperture of the Surface Detector of the Pierre Auger observatory. Finally, we will use the methods developed in the previous chapters to analyze the data of the year 2004 and will give preliminary results. (author)

  9. Radio detection of cosmic ray induced air showers at the Pierre Auger Observatory

    AERA - the Auger Engineering Radio Array - is currently being set up at the southern site of the Pierre Auger Observatory. AERA will explore the potential of the radio-detection technique to cosmic ray induced air showers with respect to the next generation of large-scale surface detectors. As AERA is co-located with the low-energy enhancements of the Pierre Auger Observatory, the observation of air showers in coincidence with the Auger surface and fluorescence detector will allow to study the radio emission processes in detail and to calibrate the radio signal. Finally, the combined reconstruction of shower parameters with three independent techniques promises new insights into the nature of cosmic rays in the transition region from 10{sup 17} to 10{sup 19} eV. Besides the detection of coherent radiation in the MHz frequency range, the setups AMBER - Air-shower Microwave Bremsstrahlung Experimental Radiometer - and MIDAS - MIcrowave Detection of Air Showers - prepare to check the possibility to detect air showers due the emission of molecular bremsstrahlung in the GHz range at the Auger site. This article presents the status of the radio-detection setups and discusses their physics potential as well as experimental challenges. Special focus is laid on the first stage of AERA which is the startup to the construction of a 20 km{sup 2} radio array.

    Pierre Pomet is a Parisian, but as all great botanists, he liked travelling and bringing back sample of drugs that he was ultimately showing during his course at the Jardin des Plantes (Royal Herbs garden in Paris). Member of druggists and groceries storekeepers’ Community, he was not allowed to establish himself as an apothecary in Paris. It is as drug expert that he wrote and published in 1694 his “General History of Drugs, concerning herbs, animals and minerals, book enriched with more than 400 copper-plate engravings designed from nature : with explanations of their various names, their countries of origin, the way to differentiate them from falsified ones, and their properties, where one can see the errors coming from Ancients and modern writers ; the whole being very useful for the public”. This book was translated into English in 1712 and German in 1717. It is part of the reference books of the 17th century for pharmacy. In his introduction, Pierre Pomet explains that his goal is to avoid for drugs errors and falsifications that very frequent at that time. The book is then dedicated not only to physicians, apothecaries or students, etc., but also to all that used drugs.

  11. Techniques for measuring aerosol attenuation using the Central Laser Facility at the Pierre Auger Observatory

    Energy Technology Data Exchange (ETDEWEB)

    Collaboration, The Pierre Auger

    2013-04-01

    The Pierre Auger Observatory in Malargüe, Argentina, is designed to study the properties of ultra-high energy cosmic rays with energies above 10(18)eV. It is a hybrid facility that employs a Fluorescence Detector to perform nearly calorimetric measurements of Extensive Air Shower energies. To obtain reliable calorimetric information from the FD, the atmospheric conditions at the observatory need to be continuously monitored during data acquisition. In particular, light attenuation due to aerosols is an important atmospheric correction. The aerosol concentration is highly variable, so that the aerosol attenuation needs to be evaluated hourly. We use light from the Central Laser Facility, located near the center of the observatory site, having an optical signature comparable to that of the highest energy showers detected by the FD. This paper presents two procedures developed to retrieve the aerosol attenuation of fluorescence light from CLF laser shots. Cross checks between the two methods demonstrate that results from both analyses are compatible, and that the uncertainties are well understood. The measurements of the aerosol attenuation provided by the two procedures are currently used at the Pierre Auger Observatory to reconstruct air shower data.

  12. System tests, initial operation and first data of the AMIGA muon detector for the Pierre Auger Observatory

    Investigating the energy region between 10{sup 17} eV and 4 x 10{sup 18} eV for primary cosmic particles will lead to a deeper understanding of the origin of cosmic rays. Effects of the transition from galactic to extragalactic origin are expected to be visible in this region. The knowledge of the composition of cosmic rays strongly depends on the hadronic interaction models, which are applied in the air shower reconstruction. Directly determining the number of muons from an air shower on ground level will improve the precision of the composition measurements by reducing the dependence on the models. The Pierre Auger Observatory is facing these challenges with an upgrade of the original detector setup. A denser sub-array of water Cherenkov detectors and a dedicated muon detector (MD) array constitute the AMIGA enhancement (Auger Muon and Infill for the Ground Array). Additional fluorescence telescopes constitute HEAT (High Elevation Auger Telescopes). Seven MD modules have been installed until mid 2012 in a first hexagon at the site of the Pierre Auger Observatory in Malarguee, Argentina. The corresponding readout electronics, and 19 more of these setups, were assembled and tested in Siegen to assure correct functionality. The detectors were incorporated in the trigger structure of the original surface detector (SD) array of the Pierre Auger Observatory and are now taking data synchronously. In the framework of this thesis, system tests have been developed, a pre-unitary cell (PUC) of seven modules has been successfully operated and their trigger has been synchronised with the SD trigger. First data from the MD have been analysed and have been combined with data from the SD.

    Full Text Available The nature and the origin of ultra-high energy cosmic rays (UHECRs, above 1017 eV, are still unknown. The Pierre Auger Observatory with its huge exposure provides us with a large set of high quality data. The analysis of these data has led to major breakthroughs in the last decade, but a coherent interpretation is still missing. To answer the open questions the Observatory has started a major upgrade, with an emphasis on improved mass composition determination using the surface detectors. The latest results and the planned detector upgrade will be presented. The expected performance and the improved physics sensitivity of the Observatory will be discussed.

  17. From The Pierre Auger Observatory to AugerPrime

    Parra, Alejandra; Martínez Bravo, Oscar; Pierre Auger Collaboration

    2017-06-01

    In the present work we report the principal motivation and reasons for the new stage of the Pierre Auger Observatory, AugerPrime. This upgrade has as its principal goal to clarify the origin of the highest energy cosmic rays through improvement in studies of the mass composition. To accomplished this goal, AugerPrime will use air shower universality, which states that extensive air showers can be completely described by three parameters: the primary energy E 0, the atmospheric shower depth of maximum X max, and the number of muons, Nμ . The Auger Collaboration has planned to complement its surface array (SD), based on water-Cherenkov detectors (WCD) with scintillator detectors, calls SSD (Scintillator Surface Detector). These will be placed at the top of each WCD station. The SSD will allow a shower to shower analysis, instead of the statistical analysis that the Observatory has previously done, to determine the mass composition of the primary particle by the electromagnetic to muonic ratio.

No presente estudo, foi realizada a análise dos parâmetros fonético-acústicos da oclusiva glotal produzidas em /k/ e /g/ por uma criança do gênero feminino, com 5 anos, que apresentava fissura de palato reparada, associada à Sequência de Pierre Robin. Para isso, foram selecionadas seis palavras em que a oclusiva velar encontrava-se na posição inicial da palavra e combinada com as vogais /a/, /i/ e /u/ na posição acentuada. Foi ainda realizado julgamento perceptivo-auditivo por três fonoaudiólogos, que apresentou concordância quanto à presença da oclusiva glotal de 100% para ambas as relações (intra e inter-juízes.

    Full Text Available By emphasizing the singular experience of the act of reading, this paper presents the work of a French legal philosopher and psychoanalyst: Pierre Legendre. Whereas this attempt could be simultaneously an impossible and irritating venture, its aim is to emphasize something that is not so often seen in legal theory: an inquiry into the nuances of the legal unconscious. In doing so, the paper opens with some references to his particular understanding of love and the spectacular as a legal resource to dominate its subjects. It continues to be peppered with several attractive spaces in which Legendre’s ecounters the binding force in the imaginary of the legal institution.

    Señalando la experiencia singular del acto de leer, este trabajo presenta la obra de un filósofo del derecho y psicoanalista francés: Pierre Legendre. A pesar de que tal proyecto pudiera constituir una empresa tan imposible como irritante, el propósito principal es resaltar un elemento que no suele observarse con frecuencia en la teoría del derecho: un recorrido por los diversos matices del inconsciente jurídico. El trabajo comienza con algunas referencias a su concepción particular del amor y del espectáculo como recursos legales para dominar a los sujetos. Y continúa con algunos espacios sugerentes donde Legendre encuentra la fuerza vinculante en el imaginario de la institución jurídica.

    Full Text Available O presente artigo aborda uma análise pouco trabalhada na literatura especializada, sobre o jardim da Villa Stein-de Monzie, também conhecida como Les Terrasses, na versão de 1926, desenvolvida por Le Corbusier e Pierre Jeanneret. Esse jardim não foi construído e essa pode ser uma das principais causas por não se encontrar uma documentação gráfica completa de seu projeto. A detalhada descrição aqui apresentada permite imaginar como teria ficado a propriedade de Les Terrasses se o projeto do jardim tivesse sido executado. A reflexão deste trabalho é uma lição sobre história da arquitetura, sobre a obra de Le Corbusier e Pierre Jeanneret e uma referência à pesquisa sobre o paisagismo moderno.

  13. Method to deduce the energy spectrum by the Pierre Auger Observatory

    Taken into account the great advantage of having a hybrid detector it has been developed a method, simulation independent, to determine the energy of the comic rays recorded by the surface detector of the Pierre Auger Observatory. The method assumes that the cosmic ray flux has the same distribution in zenith angle for all energy ranges. Therefore one can relate the calorimetric measurement of the fluorescence detector of the CR energy with a SD quantity, e.g. shower size at 1000m distance from the core, corrected for the different attenuations in the atmosphere. The method of measuring and calibrating the primary energy and the influence of reconstruction uncertainties on the energy spectrum are presented. (orig.)

    Pierre Auger Observatory operates the largest system of detectors for ultra-high energy cosmic ray measurements. Comparison of theoretical models of interactions with recorded data requires thousands of computing cores for Monte Carlo simulations. Since 2007 distributed resources connected via EGI grid are successfully used. The first and the second versions of production system based on bash scripts and MySQL database were able to submit jobs to all reliable sites supporting Virtual Organization auger. For many years VO auger belongs to top ten of EGI users based on the total used computing time. Migration of the production system to DIRAC interware started in 2014. Pilot jobs improve efficiency of computing jobs and eliminate problems with small and less reliable sites used for the bulk production. The new system has also possibility to use available resources in clouds. Dirac File Catalog replaced LFC for new files, which are organized in datasets defined via metadata. CVMFS is used for software distribution since 2014. In the presentation we give a comparison of the old and the new production system and report the experience on migrating to the new system.

    The ground array of the Pierre Auger Observatory will consist of 1600 water Cherenkov detectors, deployed over 3000 km 2 . The remoteness and large number of detectors required a simple, automatic remote calibration procedure. The primary physics calibration is based on the average charge deposited by a vertical and central throughgoing muon, determined with good precision at the detector via a novel rate-based technique and later with higher precision via charge histograms. This value is named the vertical-equivalent muon (VEM). The VEM and the other parameters needed to maintain this calibration over the full energy range and to assess the quality of the detector are measured every minute. This allows an accurate determination of the energy deposited in each detector when an atmospheric cosmic ray shower occurs

    Schmidt, David; Veberic, Darko; Roth, Markus [Karlsruhe Institute of Technology, Karlsruhe (Germany); Collaboration: Pierre-Auger-Collaboration

    2016-07-01

    To improve reconstruction of cosmic ray primary mass, the Pierre Auger Observatory is upgrading its surface detectors by installing a scintillator on top of each existing water Cherenkov tank. The different responses of the coupled detectors to the components of extensive air showers facilitates estimation of the number of muons reaching Earth's surface, which is correlated with primary mass. Geant4 and the Offline framework are used to simulate the detectors' responses, construct signal traces for individual particle components, and calculate total expected signals. This enables assessment of proposed reconstruction algorithms. An overview of the simulations and selected algorithms is presented here.

    Full Text Available Toda situação de trabalho se presta a uma dupla abordagem. É o local onde se realiza uma tarefa, pensada anteriormente e provocadora de uma intensa atividade intelectual pelo trabalhador. Mas é igualmente um momento único da vida, com suas arbitragens. Nesse caso, a tarefa não é mais vista como primeira, ela entra no 'debate de normas' que caracteriza a atividade do trabalhador sob o ângulo vital, aquele das escolhas que um ser humano não cessa de fazer. Entendemos que essas duas perspectivas correspondem, respectivamente, à de Pierre Pastré e à de Yves Schwartz. Elas se completam e enriquecem a análise: seu entrecruzamento confere, notadamente, um destaque inédito à questão das competências.There can be a dual approach to every work situation. It is the place where a task is done, one which has been planned previously and which leads the worker to an intense intellectual activity. But it is also a unique moment in life, with its arbitrations. In this case, the task is no longer seen as the first. In fact, it enters the realms of the debate of rules that characterize the worker's activity from the critical perspective, the one of the choices a human being never ceases making. We believe these two perspectives correspond to Pierre Pastré and Yves Schwartz's views, respectively. They complement and enrich the analysis: the intersection between them gives rise, notably, to an unprecedented emphasis on the issue of skills.

    French diplomat François de Rose was one of CERN’s founding fathers. Shortly after the end of World War II, on a diplomatic posting in the United States, he made the acquaintance of several leading physicists who, like him, were sitting on the Atomic Energy Commission, a body set up by the fledgling United Nations. He became friends with Robert Oppenheimer and met Isidor Rabi and the Frenchmen Lew Kowarski, Pierre Auger and Francis Perrin, all physicists driven by the conviction that developing fundamental research infrastructure was one of the keys to rebuilding Europe.   François de Rose, during CERN's official 50th Anniversary Celebrations in 2004. The United States had built itself powerful particle accelerators and the Soviet Union would soon follow suit. The growing sophistication and scale of such apparatus were beyond the means of a single European state, and this is what spurred François de Rose and his scientist friends to embark upon a tour of...

  5. Haemoglobin Pierre-Benite--a high affinity variant associated with relative polycythaemia.

    2001-12-01

    This is the second reported example of Hb Pierre--Benite (beta90 Glu-->Asp). This mutation is associated with increased oxygen affinity and polycythaemia. No instability was found and there was no charge shift detected by cellulose acetate electrophoresis at pH 8.3. The mutation was however, clearly indicated by electrospray ionization mass spectrometry (ESI MS), which showed an abnormal beta chain with a 14 Da decrease in mass. Blood volume studies documented a relative rather than a true polycythaemia and this finding has been reported in at least two other high affinity haemoglobin variants--Hb Heathrow and Hb Rahere. This finding led to delay in diagnosis because high oxygen affinity variants are conventionally considered to cause a true polycythaemia.

  6. Words, Names, Nature, Earth: On the Poetry of Pierre-Albert Jourdan

    Directory of Open Access Journals (Sweden)

    Yves Bonnefoy

    1989-11-01

    Full Text Available An ambivalence toward language is present throughout the work of Pierre-Albert Jourdan. Words are associated with the closure of a grey world; they are always arriving late, after the fact; they are veils, masks, dreams detached from truth, knowledge, and immediacy. Yet, words and names hold out the possibility of hope; they can designate the presence of beauty in the world; they can mediate the encounter of self and other. The human word signifies itself through the substance of the world and the communion of beings. At the intersection of natural reality—the center of the real for Jourdan—and of language are found the garden, the earth, places of an ephemeral, haiku like presence where the natural opens itself to the human.

  9. The mathematical career of Pierre de Fermat 1601-1665

    Mahoney, Michael Sean

    1994-01-01

    Hailed as one of the greatest mathematical results of the twentieth century, the recent proof of Fermat's Last Theorem by Andrew Wiles brought to public attention the enigmatic problem-solver Pierre de Fermat, who centuries ago stated his famous conjecture in a margin of a book, writing that he did not have enough room to show his "truly marvelous demonstration" Along with formulating this proposition-xn+yn=zn has no rational solution for n > 2-Fermat, an inventor of analytic geometry, also laid the foundations of differential and integral calculus, established, together with Pascal, the conceptual guidelines of the theory of probability, and created modern number theory. In one of the first full-length investigations of Fermat's life and work, Michael Sean Mahoney provides rare insight into the mathematical genius of a hobbyist who never sought to publish his work, yet who ranked with his contemporaries Pascal and Descartes in shaping the course of modern mathematics.

    Full Text Available El sistema de arreglo de disputas de la OME es muy estudiado y produce literatura muy divulgada. Sin embargo, hay pocos estudios empíricos sobre los perfiles de miembros de grupos especiales y del órgano de Apelación y, asimismo, su influencia en la articulación de un campo jurídico internacional al derredor de los órganos de arreglo de disputas. Ese estudio tiene el objetivo hacer disponibles algunas informaciones y analizarlas bajo la luz de algunos conceptos de la sociología de Pierre Bourdieu, en particular da de campo jurídico y de habitus, para comprender como se produce la jurificación internacional. Los resultados indican similitudes entre el campo jurídico de la omc y los campos jurídicos estatales.The WTO's dispute settlement system is a much studied subject and the literature thereon is widespread. Nevertheless, there are few empirical studies on panelists' and Appellate Body members' profiles as well as their influence on the articulation of an international legal field around the dispute resolution organizations. This study aims to make available some information on these profiles and analyze them under the light of some concepts of Pierre Bourdieu's sociology, mainly the legal field and the development of social habitus, in order to understand how international legalization of the trade law takes place. The results point out the similarities between the WTO's legal field and the state legal fields.

  12. Geothermal heating project at St. Mary's Hospital, Pierre, South Dakota. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1984-12-01

    St. Mary's Hospital, Pierre, South Dakota, with the assistance of the US Department of Energy, drilled a 2176 ft well into the Madison Aquifer ot secure 108/sup 0/F artesian flow water at 385 gpm (475 psig shut-in pressure). The objective was to provide heat for domestic hot water and to space heat 163,768 sq. ft. Cost savings for the first three years were significant and, with the exception of a shutdown to replace some corroded pipe, the system has operated reliably and continuously for the last four years.

  13. The energy spectrum of cosmic rays measured with the HEAT extension at the Pierre Auger Observatory

    International Nuclear Information System (INIS)

    Scharf, Nils Sven Sebastian

    2013-01-01

    This thesis describes the calculation of the energy spectrum of cosmic rays, that is the absolute flux of cosmic rays as a function of energy, from data of air showers observed with the HEAT (High Elevation Auger Telescopes) extension and the fluorescence detector of the Pierre Auger Observatory. The Pierre Auger Observatory is the largest observatory for the study of cosmic rays. The Pierre Auger Observatory observes air showers, that are cascades of particles that were instigated by cosmic rays hitting the Earth's atmosphere, with two different detection concepts. The surface detector samples the secondary particles of air showers that hit the ground with an array of surface detector stations, whereas the fluorescence detector measures the energy loss profile of air showers by detecting fluorescence light, produced by the air showers when they travel through the atmosphere, with optical telescopes. The properties of the cosmic rays are not directly measurable but have to be reconstructed from the observed air shower parameters. Properties of particular interest are the type of the primary cosmic ray particle, its energy and its arrival direction. HEAT is an extension to the fluorescence detector of the Pierre Auger Observatory. It is designed to lower the energy threshold by one order of magnitude down to 10 17 eV or lower. HEAT is taking data since 2010. The calculation of the absolute flux of cosmic rays needs two ingredients: the number of detected air showers as a function of shower energy and the exposure of the detector as a function of energy. The studied air shower class are hybrid events, which are events that have been detected by a fluorescence detector and at least one surface detector station. The used air showers were observed in a time period of fifteen month starting from June 2010. A first step of the analysis is the reconstruction of air showers and cosmic ray parameters from raw data. To calculate the exposure, the uptime, that is the integral

  17. Minerals sampling: sensibility analysis and correction factors for Pierre Gy's equation

    International Nuclear Information System (INIS)

    Vallebuona, G.; Niedbalski, F.

    2005-01-01

    Pierre Gy's equation is widely used in ore sampling. This equation is based in four parameters: shape factor, size distribution factor, mineralogical factor and liberation factor. The usual practice is to consider fixed values for the shape and size distribution factors. This practice does not represent well several important ores. The mineralogical factor considers only one specie of interest and the gangue, leaving out other cases such as polymetallic ores where there are more than one species of interest. A sensibility analysis to the Gy's equation factors was done and a procedure to determine specific values for them was developed and presented in this work. mean ore characteristics, associated with an insecure use of the actual procedure, were determined. finally, for a case study, the effects of using each alternative were evaluated.

  18. Investigating the physics performance of air shower universality at the Pierre Auger Observatory

    Energy Technology Data Exchange (ETDEWEB)

    Bridgeman, Ariel; Schulz, Alexander; Roth, Markus [Karlsruhe Institute of Technology (Germany); Collaboration: Pierre-Auger-Collaboration

    2016-07-01

    Recent updates to the air shower universality reconstruction of surface detector data at the Pierre Auger Observatory have reduced the bias and improved the resolution of mass-sensitive variables: the depth of shower maximum and the relative number of muons. For better-informed studies of a possible anisotropy in the arrival direction of ultra-high-energy cosmic rays, a quantification of the power of these parameters to separate a proton-like signal from background is presented. The analysis is furthered with an outlook to the detector's overall sensitivity to a proton-like signal as well as a projection of our ability to distinguish between different astrophysical flux scenarios.

    This paper discusses the correlation recently reported by the Pierre Auger Observatory (PAO) of the arrival directions of the highest energy cosmic rays with active galactic nuclei (AGN) located within 75 Mpc. It is argued that these correlating AGN do not have the power required to be the sources of those particles. It is further argued that the current PAO data disfavors giant radio-galaxies (both Fanaroff-Riley type I and II) as sources of ultra-high energy cosmic rays. The reported correlation with AGN should thus be understood as follows: the AGN trace the distribution of the local large scale structure, in which the actual sources of ultrahigh energy cosmic rays camouflage. The most promising theoretical candidates for these sources are then gamma-ray bursts and magnetars. One important consequence of the above is that one will not detect counterparts in gamma-rays, neutrinos or gravitational waves to the sources of these observed ultrahigh energy cosmic rays, since the cosmic rays are delayed by extragalactic magnetic fields on timescales approx10{sup 4}-10{sup 5} yrs much larger than the emission timescale of these sources.

    The Pierre Auger Observatory is currently in an update stage denominated AugerPrime. The Observatory will have scintillator detectors on top of each of the surface stations (WCD). The main goal of AugerPrime is to improve the studies on mass composition for ultra high energy cosmic rays, for this purpose AugerPrime will use Universality. The model will parameterize the signal in four principal components, the objective is an adequate discrimination of the muonic and electromagnetic components. We are interested in the discrimination of these two components using simulations. To do that, we are working with OfflineTrunk (the official software of the Collaboration). Our work is focused on the development of some modules for analysis and study of the signal from AugerPrime. (paper)

  9. Was Pierre Duhem an Esprit de finesse?

    Directory of Open Access Journals (Sweden)

    Víctor Manuel Hernández

    2017-06-01

    Full Text Available Although Pierre Duhem is well known for his conventionalist outlook and, in particular, for his critique of crucial experiments outlined in his thesis on the empirical indeterminacy of theory, he also contributed to the scholarship on the psychological profiles of scientists by revising Pascal’s famous distinction between the subtle mind and the geometric mind (esprits fins and esprits géométriques. For Duhem, the ideal scientist is the one who combines the defining qualities of both types of intellect. As a physicist, Duhem made important theoretical contributions to the field of thermodynamics as well as to the then-nascent physical chemistry. Due to his rejection of atomism and his unrelenting critique of Maxwell’s electrodynamics, however, in his later years, Duhem’s work was surpassed and abandoned by the dominant tendencies of physics of the time. In this essay, I will discuss whether Duhem himself can be understood through the lens of his own account of the scientist’s psychological profile. More specifically, I examine whether the subtle mind – to which he seems to assign greater cognitive value – in fact plays a key role in Duhem’s critique of the English School (école anglaise, or if his preference for the axiomatic structure of theoretical physics shows a greater affinity with the geometric mind.

In this text, known from a single 18th Century manuscript, he describes the ideal king and advises him. Thanks to its sources and many quotations and explanations, this text is quite close to biblical commentaries and sermons, but its structure and lack of Aristotelian quotations distinguish it from Gilles' of Rome famous De regimine principum. Infant Peter's is also very influenced by his political pragmatism at the beginning of the war against Castila: he recognises king's power is limited and dependant from his subjects' military and financial support.

    Peu avant sa profession chez les franciscains (12 novembre 1358, l'infant Pierre d'Aragon rédige un miroirs des princes, le De regimine principum dédié au roi Pierre IV d'Aragon son neveu et conservé dans un unique manuscrit du XVIIIe siècle. Il y dresse le portrait du souverain idéal et multiplie les conseils au roi. Par ses sources, l'abondance des citations et leur explication, ce miroir se rapproche aussi des commentaires bibliques et des sermons. Par sa structure et l'absence de références au corpus aristotélicien, il se distingue cependant de son homonyme, le De regimine principum de Gilles de Rome. Il est enfin remarquable par l'actualité et le pragmatisme politiques qui s'expriment dans son discours. L'auteur admet les limites posées au pouvoir royal, par sa dépendance militaire et financière envers les sujets au début de la guerre de Castille, et, par ses conseils, il invite Pierre le Cérémonieux à les dépasser.

  11. Measurement of the ultra high energy cosmic ray flux from data of very inclined showers at the Pierre Auger Observatory

    Dembinski, Hans Peter

    2009-01-01

    This work describes the derivation of the energy dependent flux of ultra-high energy cosmic rays from data of very inclined air showers observed with the Pierre Auger Observatory. It focuses on the event class of very inclined air showers with zenith angles larger than 60 . The lateral ground profile of these showers is muon dominated and not radially symmetric around the shower axis due to geomagnetic deflections and other effects. The dependency of this profile on the direction, energy and mass of the cosmic ray is discussed with a mixture of detailed Monte-Carlo simulations and a simplified analytical model of the air shower cascade. It is found in agreement with other studies that the normalized shape of the muon density profile is approximately universal over the range of cosmic ray energies and masses measured at the Pierre Auger Observatory, that the amplitude of the profile is almost proportional to the cosmic ray energy, and that its shower-to-shower fluctuations are sensitive to the mass composition of the cosmic rays.

    Directory of Open Access Journals (Sweden)

    Thompson J.

    2013-06-01

    Full Text Available The Pierre Auger Research and Development Array (RDA was originally designed to be the precursor of the northern Auger observatory, a hybrid array of 4400 surface detector stations and 39 fluorescence telescopes deployed over 20,000 square kilometers. It is conceived as a test bed aiming at validating an improved and more cost-effective 1-PMT surface detector design and a new peer-to-peer communication system. The array of ten surface detector stations and ten communication-only stations is currently being deployed in southeastern Colorado and will be operated at least until late 2013. It is configured in such a way that it allows testing of a new peer-to-peer communication protocol, as well as a new surface detector electronics design with a larger dynamic range aiming at reducing the distance from the shower core where saturation is observed. All these developments are expected in the short term to improve the performance of the Pierre Auger Observatory and enable future enhancements. In the longer term, it is hoped that some of these new developments may contribute to the design of a next-generation giant ground array.

    This article provides information about an important period of Piaget's formative years, those he spent in Paris from 1919 to 1921, during which he came into contact with eminent members of the French scientific and philosophical community of the time. Among these was the psychiatrist and psychologist Pierre Janet, whose genetic approach to the psychology of behaviour and ideas about the hierarchical organization of psychological functions converged with Piaget's early scientific interests and provided Piaget a conceptual framework within which to work and develop his own project of studying the genesis of knowledge.

  18. Dedication Pierre Binétruy (1955 - 2017): A scientific biography

    International Nuclear Information System (INIS)

    2017-01-01

    Pierre Binétruy, born in 1955, obtained his “state doctorate” in 1980 under the direction of Mary K. Gaillard, with a thesis on “Theoretical aspects and phenomenology of gauge theories”. From 1979 to 1986, he held several positions as postdoctoral fellow at CERN and in the United States (University of California at Berkeley, University of Florida, University of Chicago). In 1986, he was recruited as a CNRS researcher at the LAPP, Annecy-le-Vieux and 4 years later as a professor at the University of Paris XI in the Laboratory of Theoretical Physics. In 2003, he was named professor at the University Paris Diderot. His main interests evolved from high-energy particle physics (notably supersymmetry) to cosmology and gravitation, and he worked in particular on the interface between the study of the primordial Universe and the theories of fundamental interactions. Recent interests included inflation models, dark energy, and the cosmic gravitational wave background. During a prolific career, he has published seminal papers that have received more than 1000 citations each. For his research he has received several awards, such as the Thibaud Prize, the Paul Langevin Award from the SFP, and was named Berkeley Miller Professor in 1999. He was arguably one of the most brilliant theorists of his time. His memory will also remain because, to paraphrase André Malraux, he combined “spirit and courage”. He knew that it is not sufficient to seek scientific truth but that one must also have the courage to organize the community for the scientific goals that this imposes and to also fight within the institutions to defend them. Our more senior colleagues will remember the extraordinary intellectual atmosphere that animated the Supersymmetry Research Group (a CNRS “groupement de recherche”), which he initiated and directed from 1997 to 2004, transforming it into an unprecedented crossroads of experimenters and theorists, of new ideas both from theory and from

    Full Text Available As sociologias da literatura de Bourdieu e Williams estão apoiadas em dois conceitos fundamentais: “habitus” e “estruturas de sentimento”, respectivamente. E é clara a semelhança entre eles: ambos tentam traduzir uma espécie de consciência prática adquirida pelos agentes sociais a partir de um processo particular de socialização. Para o primeiro, o “habitus” é internalizado na experiência vivida num campo específi co; ao passo que, para o segundo, tal consciência é formada no interior dos grupos culturais. Nesse sentido, ambas as noções dizem respeito a um conjunto de valores compartilhados que aproximam e afastam certos agentes uns dos outros, criando solidariedade e rivalidades. Esta comunicação pretende demonstrar que, apesar das diferenças que existem, os conceitos dos autores não supervalorizam nem a reprodução nem a mudança social, mas, ao contrário, tentam explicar esses fenômenos como jogo dialético. Palavras-chave: Pierre Bourdieu. Raymond Williams. Sociologia da literatura. “Habitus”. Estruturas de sentimento. The literature sociologies of Bourdieu and Williams are structured in two fundamental concepts: “habitus” and “sentiment structures”, respectively. It’s very clear the resemblance between them: both try to translate a kind of practical conscience, acquired by the social agents from a particular socializing process. To the fi rst, the “habitus” is internalized in the living experience of a specifi c fi eld; while that to the second that conscience is formed in the interior of cultural groups. In this sense, both ideas talk about shared values which approximate and withdraw some agents one from the others, creating solidarity and competition. This text intends to show that, despite of the existing differences, the authors concepts don’t overestimate neither the reproduction, nor the social change, but, otherwise, try to explain these phenomena as a dialectic game.

    We report a measurement of the proton-air cross section for particle production at the center-of-mass energy per nucleon of 57 TeV. This is derived from the distribution of the depths of shower maxima observed with the Pierre Auger Observatory: systematic uncertainties are studied in detail. Analyzing the tail of the distribution of the shower maxima, a proton-air cross section of [505 {+-} 22(stat){sub -36}{sup +28}(syst)] mb is found.

  4. Ermeneutica letteraria ed esercizi spirituali: Wolfgang Iser e Pierre Hadot

    Directory of Open Access Journals (Sweden)

    Carmen Dell'Aversano

    2017-06-01

    Full Text Available This paper aims to highlight some interesting convergences between the theory of the meaning-construction of the literary text proposed by Iser in The Act of Reading and Pierre Hadot’s work on the hermeneutics of the text in ancient philosophy. As we know, Hadot interprets the specificities of the ancient philosophical text as functional to guide the mind of the reader in a path that does not only have a cognitive purpose, but rather a spiritual one. The concept of «spiritual excercise», central to Hadot’s work, presents similarities ­– that are potentially very productive – to the model of the use of the literary text in Iser. Moreover, it is apt to show the extraordinary theoretical importance of a series of details, which are seemingly quite technical. In particular, a dialogue between the two approaches of Iser and Hadot allows posing in a new way a question that literary theory typically marginalizes: that of the pragmatics of the literary text.

  5. Le Corbusier, Pierre Chareau and two masterpieces of modern architecture

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Le Corbusier and Pierre Chareau are famously responsible for two projects considered iconic of modern architecture: Villa Savoye and Maison de Verre. Both are coeval and commissioned by clients with the same socioeconomic profile – the French haute bourgeoisie –, and with similar needs. Villa Savoye is a single family home, while Maison de Verre houses both residential and medical clinic functions in the same building structure. However, this difference does not interfere in our intended analysis. By comparing the client-architect relationships in both projects – Le Corbusier/Savoye and Chareau/Dalsace – we raise  questions regarding the professional behavior that modern architects have arrogated to themselves: to revolutionize customs and practices. The projects are modern and diverse responses to similar requests. In both cases, the role of women is indicative of their influence in that particular historical context as opinion setters. The house is the locus of the female dominium, and as such expresses women’s tastes and habits.

    Atmospheric conditions at the site of a cosmic ray observatory must be known for reconstructing observed extensive air showers. The Global Data Assimilation System (GDAS) is a global atmospheric model predicated on meteorological measurements and numerical weather predictions. GDAS provides altitude-dependent profiles of the main state variables of the atmosphere like temperature, pressure, and humidity. The original data and their application to the air shower reconstruction of the Pierre Auger Observatory are described. By comparisons with radiosonde and weather station measurements obtained on-site in Malargue and averaged monthly models, the utility of the GDAS data is shown.

    To interpret the mean depth of cosmic ray air shower maximum and its dispersion, we parametrize those two observables as functions of the first two moments of the ln A distribution. We examine the goodness of this simple method through simulations of test mass distributions. The application of the parameterization to Pierre Auger Observatory data allows one to study the energy dependence of the mean ln A and of its variance under the assumption of selected hadronic interaction models. We discuss possible implications of these dependences in term of interaction models and astrophysical cosmic ray sources.

    The Pierre Auger Observatory combines the air shower fluorescence and surface array methods to study ultra-high energy cosmic rays. As the energy scale of the experiment is derived from calorimetric measurements by the fluorescence telescopes, their accurate calibration is of primary importance to all Auger data. We discuss a novel calibration method based on a remotely flown drone equipped with a specially designed light source that mimics a snapshot of an air shower traversing the atmosphere. Several drone measurement campaigns have been performed to study the properties of the Auger fluorescence telescopes and to derive an end-to-end calibration. We give an overview of the measurements and present the basic analysis chain as well as the first results of an independent cross-check of the Auger energy scale.

    The possible existence of axions in the universe means that they are a candidate for (very) cold dark matter, as another axion pioneer, Pierre Sikivie, from the University of Florida explained during the first Joint ILIAS-CAST-CERN Axion Training workshop. He also described the technique that he invented in 1983 for detecting axions. The idea is that axions in the galactic halo may be resonantly converted to microwave photons in a cavity permeated by a strong magnetic field.

    The surface detector array of the Pierre Auger Observatory provides information about the longitudinal development of the muonic component of extensive air showers. Using the timing information from the flash analog-to-digital converter traces of surface detectors far from the shower core, it is possible to reconstruct a muon production depth distribution. We characterize the goodness of this reconstruction for zenith angles around 60° and different energies of the primary particle. From these distributions, we define Xmaxμ as the depth along the shower axis where the production of muons reaches maximum. We explore the potentiality of Xmaxμ as a useful observable to infer the mass composition of ultrahigh-energy cosmic rays. Likewise, we assess its ability to constrain hadronic interaction models.

    We present a combined fit of a simple astrophysical model of UHECR sources to both the energy spectrum and mass composition data measured by the Pierre Auger Observatory. The fit has been performed for energies above 5 ⋅ 10{sup 18} eV, i.e. the region of the all-particle spectrum above the so-called 'ankle' feature. The astrophysical model we adopted consists of identical sources uniformly distributed in a comoving volume, where nuclei are accelerated through a rigidity-dependent mechanism. The fit results suggest sources characterized by relatively low maximum injection energies, hard spectra and heavy chemical composition. We also show that uncertainties about physical quantities relevant to UHECR propagation and shower development have a non-negligible impact on the fit results.

  16. Auger ACCESS—Remote Controlling and Monitoring the Pierre Auger Observatory

    2013-10-01

    Ultra high energy cosmic rays are the most energetic particles in the universe. They are measured to have energies of up to 1020 eV and occur at a rate of about once per square kilometer per century. To increase the probability of detecting one of these events, a huge detector covering a large area is needed. The Pierre Auger Collaboration build up an observatory covering 3000 square kilometers of the Pampa Amarilla close to Malargüe for this purpose. Until now, the Auger Observatory has been controlled exclusively via the local network for security and performance reasons. As local operation is associated with high travel costs, the Auger ACCESS project, started in 2005, has constructed a secure, operable and sustainable solution for remote control and monitoring. The implemented solution includes Grid technologies for secured access and infrastructure virtualization for building up a fully featured testing environment for the Auger Observatory. Measurements showed only a negligible delay for communicating with the observatory in Argentina, which allows the establishment of remote control rooms in the near future for full remote operation and remarkable cost reduction.

    Full Text Available Verifica a extensão dos aportes botânicos de Pierre-François-Xavier de Charlevoix em Histoire et description générale de la Nouvelle France em relação a trabalhos de pesquisadores anteriores, suas valorações das representações iconográficas e discursivas e aplicabilidade no projeto de colonização francesa. Investiga-se o que o levou a preterir o modelo taxionômico de Lineu e o que pretendia com seu catálogo de curiosidades botânicas. O desenlace de sua trajetória filosófico-religiosa permite compreender seu posicionamento no quadro de classificação da natureza, os sentidos das informações etnológicas, as formas de apropriação intelectual e os usos da iconografia botânica e do discurso como propaganda político-emotiva para incentivar a ocupação colonial.The article explores the botanical contributions of Pierre-François-Xavier de Charlevoix's book Histoire et description générale de la Nouvelle France vis-à-vis the contributions of previous researchers, his use of iconographic and discursive representations and its relevance to the project of French colonization. It investigates why he refused Linnaeus' taxonomic model and what he intended with his catalogue of botanical curiosities. The unfolding of his philosophical and religious trajectory allows to understand his stance regarding the classification of nature, the meanings of ethnological information, his forms of intellectual appropriation, and his use of discourse and botanical iconography as political and emotional propaganda to encourage colonial settlement.

    Aerosols play an important role in radiative transfer processes involved in different fields of study. In particular, their influence is crucial in the attenuation of light at astronomical and astrophysical observatories, and has to be taken into account in light transfer models employed to reconstruct the signals. The Andean Argentinean region is increasingly being considered as a good candidate to host such facilities, as well as the ones for solar-energy resources, and an adequate knowledge of aerosols characteristics there is needed, but it is not always possible due to the vast area involved and the scarce atmospheric data at ground. The aim of this work is to find correlations between aerosol data and particle trajectories that can give an insight into the origin and behaviour of aerosols in this zone and can be employed in situations in which one does not have local aerosol measurements. For this purpose, an aerosol spectrometer and dust monitor (Grimm 1.109) was installed at the Pierre Auger Observatory of ultra-high-energy cosmic rays, to record aerosol concentrations in different size intervals, at surface level. These measurements are analysed and correlated with air mass trajectories obtained from HYSPLIT (NOAA) model calculations. High aerosol concentrations are registered predominantly when air masses have travelled mostly over continental areas, mainly from the NE direction, while low aerosol concentrations are found in correspondence with air masses coming from the Pacific Ocean, from the NW direction. Different size distribution patterns were found for the aerosols depending on their origin: marine or continental. This work shows for the first time the size distribution of aerosols registered at the Pierre Auger Observatory. The correlations found between mass and particle concentrations (total and for different size ranges) and HYSPLIT air mass trajectories, confirm that the latter can be employed as a useful tool to infer the sources, evolution

    The Pierre Auger Observatory detects the atmospheric showers induced by cosmic rays of ultra-high energy (UHE). It is the first one to use the hybrid technique. A set of telescopes observes the fluorescence of the nitrogen molecules on clear moonless nights, giving access to the longitudinal profile of the shower. These telescopes surround a giant array of 1600 water Cherenkov tanks (covering more than 3000 km2), which works continuously and samples the particles reaching the ground (mainly muons, photons and electrons/positrons); the light produced within the water is recorded into FADC (Fast Analog to Digital Convertes) traces. A subsample of hybrid events provides a cross calibration of the two components. We describe the structure of the Cherenkov detectors, their sensitivity to different particles and the information they can give on the direction of origin, the energy and the nature of the primary UHE object; we discuss also their discrimination power for rare events (UHE photons or neutrinos). To cope with the variability of weather conditions and the limitations of the communication system, the procedures for trigger and real time calibration have been shared between local processors and a central acquisition system. The overall system has been working almost continuously for 10 years, while being progressively completed and increased by the creation of a dense "infill" subarray.

    The large sample of data collected by the Pierre Auger Observatory has led to a significant improvement over previous measurements on the energy spectrum of cosmic rays. We observe a suppression of the flux at the highest energy with a significance of more than 6 standard deviations. The spectral index γ of the flux, J∝E -γ , at energies between 4x10 18 eV and 4x10 19 eV is 2.69±0.02 (stat) ±0.06 (syst), steepening to 4.2±0.4 (stat) ±0.06 (syst) at higher energies, consistent with the prediction by Greisen and by Zatsepin and Kuz'min. Observations of cosmic rays by the fluorescence detector allowed the extension of the energy spectrum to lower energies, where the efficiency of the surface detector is less then 100% and a change in the spectral index is expected.

    This study aimed to highlight, illustrate, describe, and comment on the presence of the health category in the work of Pierre Bourdieu, by underlining the themes traditionally related to the sociology of the body. After a systematic analysis of his work in the sociology of medicine and health, the article also addresses the main vehicle for his line of thought, namely Actes de la Recherche en Sciences Sociales, viewed here as the prime channel for most of the research taking Bourdieu's "genetic structuralism" as the main theoretical reference. We analyze the articles published from 1975 to 2001, from the thematic and theoretical/conceptual perspective, by comparing the changes appearing in this journal in opposition to the model previously adopted by the Revue Française de Sociologie.

    Simultaneous measurements of air showers with the fluorescence and surface detectors of the Pierre Auger Observatory allow a sensitive search for EeV photon point sources. Several Galactic and extragalactic candidate objects are grouped in classes to reduce the statistical penalty of many trials from that of a blind search and are analyzed for a significant excess above the background expectation. The presented search does not find any evidence for photon emission at candidate sources, and combined p -values for every class are reported. Particle and energy flux upper limits are given for selected candidate sources. These limits significantly constrain predictions of EeV proton emission models from non-transient Galactic and nearby extragalactic sources, as illustrated for the particular case of the Galactic center region.

    With the Pierre Auger Observatory, being the largest air shower detector setup in the world, ultra-high-energy cosmic rays are studied with full trigger efficiency above E=3 x 10{sup 18} eV. In order to achieve a more detailed understanding of cosmic ray physics at lower energies down to E∼10{sup 17} eV, e.g. the transition from galactic to extragalactic sources and a possible change in the composition of the primary cosmic rays, the observatory is currently upgraded by the AMIGA enhancement (Auger Muons and Infill for the Ground Array). The muon counters of AMIGA, buried underground, will allow for dedicated measurements of the number of muons in air showers, thus increasing the precision in determining the type of the primary particle. Until middle of 2012, eight prototype muon counters of the AMIGA enhancement were installed at the experimental site of the Pierre Auger Observatory at Malargue, Argentina, forming one detector hexagon referred to as the pre-unitary cell (PUC). Each muon counter comprises a highly modular electronics readout system. Following the production of these systems, tests of single components as well as of the full readout electronics were carried out. In the framework of this thesis dedicated firmware, allowing for the commissioning and first data taking with the PUC, has been developed and tested. Among other features, this firmware includes a self-trigger of the muon counters as well as algorithms for the synchronization of the muon detector (MD) with the existing surface detector (SD) array. The functionality and performance of the electronics readout system with regard to this firmware has been investigated. In addition, first analyses of combined MD and SD data have been performed.

    Since data-taking began in January 2004, the Pierre Auger Observatory has been recording the count rates of low energy secondary cosmic ray particles for the self-calibration of the ground detectors of its surface detector array. After correcting for atmospheric effects, modulations of galactic cosmic rays due to solar activity and transient events are observed. Temporal variations related with the activity of the heliosphere can be determined with high accuracy due to the high total count rates. In this study, the available data are presented together with an analysis focused on the observation of Forbush decreases, where a strong correlation with neutron monitor data is found.

    Full Text Available In the Festschrift zum 70. Geburtstag von Anthony R. Birley, Richard Talbert published an article about a map which, as the author affirms, skipped the attention of the historians. In fact, it is a set of nine maps, at a scale of approximately 1:3,400,000, illustrating, according to a modern representation, the Roman world. The geographical space represented starts from the Antonine Wall and Britain in the left side and ends to Hierasycaminos on the border between Egypt and Nubia. The maps are part of a two volume project, commissioned by Agricol Fortia d’Urban (1756-1843. The book, entitled Recueil des Itinéraires Anciens comprenant l’Itinéraire d’Antonin, la Table de Peutinger et un choix des périples grecs, avec dix cartes dressées par M. le Colonel Lapie, was published in 1845 by the Imprimerie Royale, Paris. The maps were created by one of the most famous French cartographer of the XIXth century, Pierre M. Lapie (1799-1850. Our study discusses the information from this maps regading Moesia and the accuracy of the cartographer during the process of mapping the Roman roads from the south-danubian province.

  20. The sociologist and the state. An assessment of Pierre Bourdieu's sociology.

    Science.gov (United States)

    Schinkel, Willem

    2015-06-01

    This paper provides an assessment of Pierre Bourdieu's sociology based on a reading of his posthumously published lectures on the state in Sur l'État. It argues that the state was a foundational element in Bourdieu's rendition of the symbolic order of everyday life. As such, the state becomes equally pivotal in Bourdieu's sociology, the applicability of which rests on the existence of the state, which stabilizes the social fields and their symbolic action that constitute the object of sociology. The state, which Bourdieu considers a 'meta'-ordering principle in social life, ensures that sociology has a well-ordered object of study, vis-à-vis which it can posit itself as 'meta-meta'. The state thus functions as an epistemic guarantee in Bourdieu's sociology. A critical analysis of Bourdieu's sociology of the state offers the chance of a more fundamental overall assessment of Bourdieu's conception of sociology that has relevance for any critical sociological perspective that rests on the assumption of a meta-social entity, such as the state in Bourdieu's work, as a final ordering instance. © London School of Economics and Political Science 2015.

  1. New electronics for the surface detectors of the Pierre Auger Observatory

    The Pierre Auger Observatory is the largest installation worldwide for the investigation of ultra-high energy cosmic rays. Air showers are detected using a hybrid technique with 27 fluorescence telescopes and 1660 water-Cherenkov detectors (WCD) distributed over about 3000 km{sup 2}. The Auger Collaboration has decided to upgrade the electronics of the WCD and complement the surface detector with scintillators (SSD). The objective is to improve the separation between the muonic and the electron/photon shower component for better mass composition determination during an extended operation period of 8–10 years. The surface detector electronics records data locally and generates time stamps based on the GPS timing. The performance of the detectors is significantly improved with a higher sampling rate, an increased dynamic range, new generation of GPS receivers, and FPGA integrated CPU power. The number of analog channels will be increased to integrate the new SSD, but the power consumption needs to stay below 10 W to be able to use the existing photovoltaic system. In this paper, the concept of the additional SSD is presented with a focus on the design and performance of the new surface detector electronics.

  4. Measurement of the muon content in air showers at the Pierre Auger Observatory

    2016-01-01

    Full Text Available The muon content of extensive air showers produced by ultra-high energy cosmic rays is an observable sensitive to the composition of primary particles and to the properties of hadronic interactions governing the evolution of air-shower cascades. We present different methods for estimation of the number of muons at the ground and the muon production depth. These methods use measurements of the longitudinal, lateral, and temporal distribution of particles in air showers recorded by the detectors of the Pierre Auger Observatory. The results, obtained at about 140 TeV center-of-mass energy for proton primaries, are compared to the predictions of LHC-tuned hadronic-interaction models used in simulations with different primary masses. The models exhibit a deficitin the predicted muon content. The combination of these results with other independent mass composition analyses, such as those involving the depth of shower maximum observablemax, provide additional constraints on hadronic-interaction models for energies beyond the reach of the LHC.

    Full Text Available This paper tries to draw a new perspective on Pierre Naville’s work, essential for the consolidation of the Sociology of Labour in France but nevertheless almost unknown and frequently misunderstood in Spain. Our interpretation is based on the debates held by Naville with his collaborators about the theoretical and methodological positions adopted by this branch of studies at the very first moment of its institutionalization in the sixties. These debates can be summarized in three main lines: (1 the criticism to the reduction of the object «work» into «post, process and situation». (2 The questioning of the analytical frame which studied the evolution of «work» taking for granted the natural unity among the producer, his tool, his activity and his product, unity represented by the craftsman. (3 The criticism to the methodological procedures that eluded both the problem of time — taking only into account the single instant— and measure —ignoring the study of salary—. These three splits contribute to shift the problem of waged labour from the technical and organizational conformation of posts and processes of work and the social and institutional forms of employments and socially built job markets, to the relationships between works and work force, posts and jobs, technical and social divisions of work, considering that this relationships structure the subject’s life (times of work/leisure/recovering. Finally, we argue that this shift can be useful to outline a theoretical link between the two shores existing in current European Sociology of Labour: a Sociology based in the work situation and a Sociology based in the labour marketEste artículo traza un particular itinerario sobre la obra de Pierre Naville, autor esencial en las primeras etapas de la consolidación de la sociología del trabajo en Francia pero que, a pesar de ello, resulta aún mayormente desconocido y no siempre bien interpretado en nuestro país.

    Full Text Available La noción de campo desempeñó un papel central en los proyectos científicos de Kurt Lewin y Pierre Bourdieu. En este artículo hacemos un análisis comparativo del uso teórico y metodológico que hicieron de este concepto en la producción de su fecunda obra en los campos de la psicología y de la sociología, respectivamente. Para ello nos hemos centrado en cinco cuestiones cruciales que de modo explícito plantearon estos dos investigadores en la elaboración de su teoría de campo: la ruptura con las objetivaciones parciales, la construcción del objeto, la dinámica interna de los campos, la delimitación de sus fronteras y la representación matemática de los hechos psicológicos y sociológicos. Concluimos con una síntesis en la que ponemos de relieve algunas importantes coincidencias y diferencias en la teoría de campo de Kurt Lewin y Pierre Bourdieu. Ambos le asignaron funciones epistemológicas similares, pero podemos apreciar en Lewin un mayor mimetismo respecto a la noción de campo proveniente de la física y sus posibilidades de formulación matemática, mientras que en Bourdieu la noción de campo es inseparable de las de habitus y capital, lo que facilita un análisis más integrado de los fenómenos micro y macrosociales, una apreciación más sofisticada de sus dimensiones temporales y criterios más precisos para establecer los límites de un campo.

    Polifonie en kontrapunt: Meganismes van verleiding in die dagboeke van Helen Hessel en Henri Pierre Roché. Henri Pierre Roché (1879–1959, outeur van Jules et Jim, word beskryf as ‘n sosiale koppelaar, ‘n model-liefhebber van alles en nog wat, ‘n versamelaar van vroue en kuns en een van die mees produktiewe dagboekskrywers en aktiewe minnaars in die opgetekende geskiedenis. Roché het ‘n reeks sketse oor Don Juan gepubliseer en was geboei deur die figuur van die verleier. In sy twintigs beplan hy om sy lewe te wy aan die skepping van ‘n œuvre wat die morele, intellektuele, sosiale en seksuele verhoudings tussen mans en vrouens sou ondersoek. Ter bereiking van hierdie doel, rig hy sy lewe in as laboratorium waarin werklike ondervindinge dien as hoofbron van inligting. Sy dagboek strek oor sestig jaar en is ryk aan verhale van verleiding. Desnieteenstaande bly die mees intense en boeiende intrige van verleiding en verraad steeds sy verhouding met Helen Hessel. Aan die begin van hulle verhouding, stel Roché voor dat sy ook ‘n dagboek hou van hulle hartstogtelike liefde. Helen Hessel se dagboek, geskryf in Frans, Duits en Engels, reflekteer die drama van verleiding en funksioneer op verskillende vlakke: realisties, visionêr, ten volle geabsorbeer in haar eie gedagtes en emosies en tóg krities jeens haarself en ander. ‘n Vergelyking van die twee dagboeke skep ‘n fassinerende, digte tekstuur wat die binnewerkings blootlê van verleiding in aksie. Die kontrapunt geskep deur hierdie twee interafhanklike stemme word nóg meer kompleks namate ‘n mens bewus word van die intertekstuele verwysings wat bydra tot die ontluikende polifonie van geskrewe liefde en lewe.

    2011-01-01

    Before Vivant Denon, the dealer Jean-Baptiste-Pierre Lebrun played a crucial role in the creation of the Louvre collections, despite the revolutionary discourse which opposed the market to the museum. Lebrun's position as a polemicist is interpreted here as a strategy of self-presentation which made possible the controversial birth of the figure of the museum expert. With Lebrun, the Louvre imposed itself as a public space of artistic expertise, where values imported from the market - such as attributionism, materiality, and authenticity - became prominent in the evaluation of paintings.

  14. Study of the composition of ultra-high energy cosmic rays detected by the Pierre Auger Observatory and analysis of the associated hadronic mechanisms

    Garrido, X.

    2008-01-01

    Ultra high energy cosmic rays (UHECR), i.e. E ≥ 1 EeV, raise many questions about their origin and constitute a challenge to modern physics. These cosmic rays entering the atmosphere dissipate their huge energy by generating a shower of secondary particles whose development is significantly different depending on the nature of the primaries. The study of the composition of UHECR is therefore a major interest both in understanding the hadronic processes which govern the evolution of showers and in identifying the sources of this radiation. Given its hybrid structure and the size of its unmatched network of ground detectors, the Pierre Auger Observatory can provide clear answers to the issues raised by UHECR. In this thesis, we are particularly interested in the muon component of air showers. First, we show how the hadronic parameters define the production of muons. Then we present an original method to extract this muon component and deduce the implications on the composition of UHECR. The results of this approach suggest a transition from a heavy composition to a light one when the energy increases. Finally, we address the measurement of cosmic-air cross section and present the first results derived from the Pierre Auger Observatory data. (author)

    This volume is a collection of selected papers by Pierre van Baal on the subject of quark-gluon interactions. He concentrates on semi-perturbative phenomena that occur when these particles are confined to a box. He introduced in 1998 the notion of calorons to explain what happens in the high temperature phase of the quark-gluon plasma. Van Baal's discoveries of the mathematical intricacies of twisted gluon field configurations have left their mark on the field, opening new directions for numerical simulations. This reprint is intended to be a comprehensive introduction for all those who wish to have deeper understanding of quark-gluon dynamics.

    Cosmic radiations of ultra high energy (RCUHE, beyond 10{sup 18} eV) are difficult to study because of their low flux on the earth surface: about 1 photon per year and per km{sup 2}. The observatory Pierre Auger proposes to study RCUHE by designing 2 sites of 3000 km{sup 2} (one in each hemisphere) allowing the observation of the shower initiated by cosmic radiation by using 4 fluorescence telescopes and a network of 1600 Cherenkov detectors. The identification of the primary particle is a very delicate point, the detection of neutrino or photon at these energies would bring valuable information for the understanding of potential sources of RCUHE. The first part of this work presents the project and its assets to perform its task. The second part is dedicated to the description of the Cherenkov detectors, of the trigger system, and of the centralized data acquisition system. The last part present the prototype installation that is under construction at Macargue in Argentina. (A.C.)

    El Detector de Superficie del Observatorio Pierre Auger es sensible a tau neutrinos que cruzan la Tierra de forma rasante interactuando en su corteza. Los leptones tau que surgen de las interacciones via corriente cargada pueden emerger de la Tierra y decaer en la atmósfera produciendo lluvias de partículas casi horizontales que contienen una componente electromagnética significativa. En esta tesis se diseñan técnicas de reconstrucción y de identificación que permiten distinguir estas lluvias...

    The surface detector array of the Pierre Auger Observatory is sensitive to Earth-skimming tau neutrinos that interact in Earth's crust. Tau leptons from nu(tau) charged-current interactions can emerge and decay in the atmosphere to produce a nearly horizontal shower with a significant electromagnetic component. The data collected between 1 January 2004 and 31 August 2007 are used to place an upper limit on the diffuse flux of nu(tau) at EeV energies. Assuming an E(nu)(-2) differential energy spectrum the limit set at 90% C.L. is E(nu)(2)dN(nu)(tau)/dE(nu)<1.3 x 10(-7) GeV cm(-2) s(-1) sr(-1) in the energy range 2 x 10(17) eV< E(nu)< 2 x 10(19) eV.

    Full Text Available En este artículo se ofrece una aproximación al concepto de reflexividad y a su función en la Teoría Social de Pierre Bourdieu. Se analizan los cambios sufridos por el marco conceptual de la reflexividad en el curso de la trayectoria del sociólogo francés, desde el significado puramente epistemológico de su primera época al contenido ético que recibe en su obra más tardía. La reflexividad es entonces entendida como una 'tecnología del yo', por utilizar las palabras de Foucault. De este modo se intenta explicar el giro é tico del último Bourdieu y el estilo de pensamiento promovido por su equipo de investigación.

    With the Auger Engineering Radio Array (AERA) at the Pierre Auger Observatory radio emission of extensive air showers induced by ultra high energy cosmic rays is observed. Characteristics of the primary cosmic ray, e.g., arrival direction, mass or energy, can be measured this way. To produce high quality data, the detector needs to be well understood and calibrated. A useful tool for calibration campaigns is an octocopter. With it, a calibration source can be placed above the array, which makes this a very flexible method useful for different types of calibrations. Special focus is put on the position reconstruction and the position accuracy of the octocopter during the calibration flights. A new optical method using two cameras for these position reconstructions is presented. Results of a measurement campaign in spring 2015 are presented. In this campaign, the sensitivity of the AERA stations as well as timing characteristics were measured. The results of the sensitivity measurement are compared to simulations.

    The Pierre Auger Observatory is a multi-national organization for research on ultra-high energy cosmic rays. The Southern Auger Observatory (Auger-South) in the province of Mendoza, Argentina, has been completed in 2008. First results on the energy spectrum, mass composition and distribution of arrival directions on the southern sky are really impressive. The planned Northern Auger Observatory in Colorado, USA, (Auger-North) will open a new window into the universe and establish charged particle astronomy to determine the origin and nature of ultra-high energy cosmic rays. These cosmic particles carry information complementary to neutrinos and photons and to gravitational waves. They also provide an extremely energetic beam for the study of particle interactions at energies that thirty times higher than those reached in terrestrial accelerators. The Auger Observatory is a hybrid detector consisting of a Surface Detector (SD) and an atmospheric Fluorescence Detector (FD). The hybrid data set obtained when both...

  6. Conspiracies of immanence: Paul Tillich, Pierre Teilhard de Chardin and C.G. Jung.

    Dourley, John

    2015-02-01

    Jung's psychology proffers a sustained reflection on the traditional religious question of the relation of divine transcendence to immanence. On this issue his psychology affirms a position of radical immanence in its contention that the experience of divinity is initially wholly from within. Though this position remains on the periphery of religious and theological orthodoxy Jung is not alone in holding it among moderns. Paul Tillich adopts a similar stance with his controlling symbols of the divine as 'Ground of Being' and 'Depth of Reason'. Pierre Teilhard de Chardin understands divinity as the experiential energy of evolution itself working within nature and humanity toward greater configurations of universal communion as the basis of community. All of Jung's master symbols of individuation assume such an understanding of immanence uniting individual and totality. His psychology strongly suggests and contributes to the current emergence of a new religious sensitivity based on the awareness of the intra-psychic origin of all religions. In his later writings he held out such a position as a significant alternative to genocide. © 2015, The Society of Analytical Psychology.

  7. Infusing fundamental cause theory with features of Pierre Bourdieu's theory of symbolic power.

    2018-02-01

    The theory of fundamental causes is one of the more influential attempts to provide a theoretical infrastructure for the strong associations between indicators of socioeconomic status (education, income, occupation) and health. It maintains that people of higher socioeconomic status have greater access to flexible resources such as money, knowledge, prestige, power, and beneficial social connections that they can use to reduce their risks of morbidity and mortality and minimize the consequences of disease once it occurs. However, several key aspects of the theory remain underspecified, compromising its ability to provide truly compelling explanations for socioeconomic health inequalities. In particular, socioeconomic status is an assembly of indicators that do not necessarily cohere in a straightforward way, the flexible resources that disproportionately accrue to higher status people are not clearly defined, and the distinction between socioeconomic status and resources is ambiguous. I attempt to address these definitional issues by infusing fundamental cause theory with features of a well-known theory of socioeconomic stratification in the sociological literature-Pierre Bourdieu's theory of symbolic power.

    This is a report of a short-term, pastoral counselling group conducted with Jewish internees in a high security prison in Israel. It was held as an adjunct to daily secular individual and group counselling and rehabilitation run by the Department of Social Work. Pastoral counselling employed spiritual and psychosocial methodologies to reduce anger, improve prisoner frustration tolerance, and develop a sense of self-efficacy and communal identity. It combined semi-didactic scriptural input with Pierre Janet's personality model, Fritz Perls' gestalt therapy, and analysis of the group process. © The Author(s) 2015 Reprints and permissions:sagepub.co.uk/journalsPermissions.nav.

    Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with E ≥ 6 x 10 19 eV by analyzing cosmic rays with energies above E ≥ 5 x 10 18 eVarriving within an angular separation of approximately 15 circle . We characterize the energy distributions inside these regions by two independent methods, one searching for angular dependence of energy-energy correlations and one searching for collimation of energy along the local system of principal axes of the energy distribution. No significant patterns are found with this analysis. The comparison of these measurements with astrophysical scenarios can therefore be used to obtain constraints on related model parameters such as strength of cosmic-ray deflection and density of point sources.

    The DOE Spent Fuel and Waste Technology (SWFT) R&D Campaign is supporting research on crystalline rock, shale (argillite) and salt as potential host rocks for disposal of HLW and SNF in a mined geologic repository. The distribution of these three potential repository host rocks is limited to specific regions of the US and to different geologic and hydrologic environments (Perry et al., 2014), many of which may be technically suitable as a site for mined geologic disposal. This report documents a regional geologic evaluation of the Pierre Shale, as an example of evaluating a potentially suitable shale for siting a geologic HLW repository. This report follows a similar report competed in 2016 on a regional evaluation of crystalline rock that focused on the Superior Province of the north-central US (Perry et al., 2016).

  14. Pierre-Jean Mariette, enlightened art connoisseur and scholar of art history

    Full Text Available Review of Mariette and the Science of the Connoisseur in Eighteenth-Century Europe by Kristel Smentek, Farnham: Ashgate, 2014. In her book Smentek brings back to life the rich scope of economic and scholarly activities and social ambitions employed by the art dealer and collector of European renown, Jean-Pierre Mariette (1694-1774. By concentrating on the various artistic media in which he was primarily involved, she each time singles out an aspect of Mariette’s expertise. Economic and social shrewdness in the case of printmaking, the very core of his art connoisseurship in the case of drawing, and his art-historical scholarship in the case of gem engraving. In spite of the diverse connections she here creates between artistic medium and expertise, Smentek makes abundantly clear that the scientific method of art connoisseurship was underlying the employment of all these artistic media, which favoured empirical analysis in the historical understanding of art. She thereby makes a highly convincing case of the ways in which Mariette’s practices changed the terms in which the artistic past was scrutinized. On this basis it seems only logical to further research the impact of Mariette’s practices on art-scholarly projects initiated elsewhere in Europe and the ways it contributed to the emergence of art history as a modern discipline.

    The Pierre Auger Observatory, located in the Province of Mendoza in Argentina, is making good progress in understanding the nature and origin of the ultra-high energy cosmic rays. Using a hybrid detection technique, based on surface detectors and fluorescence telescopes, it provides large statistics, good mass and energy resolution, and solid control of systematic uncertainties. One of the main challenges for the fluorescence detection technique is the understanding of the atmosphere, used as a giant calorimeter. To minimize as much as possible the systematic uncertainties in fluorescence measurements, the Auger Collaboration has developed an extensive atmospheric monitoring program. The purpose of this work is to improve our knowledge of the atmospheric aerosols, and their effect on fluorescence light propagation. Using a modelling program computing air mass displacements, it has been shown that nights with low aerosol concentrations have air masses coming much more directly from the Pacific Ocean. For the first time, the effect of the aerosol size on the light propagation has been estimated. Indeed, according to the Ramsauer approach, large aerosols have the largest effect on the light scattering. Thus, the dependence on the aerosol size has been added to the light scattering parameterizations used by the Auger Collaboration. A systematic overestimation of the energy and of the maximum air shower development X max is observed. Finally, a method based on the very inclined laser shots fired by the Auger central laser has been developed to estimate the aerosol size. Large aerosol sizes ever estimated at the Pierre Auger Observatory can now be probed. First preliminary results using laser-shot data collected in the past have identified a population of large aerosols. (author)

    An upper limit of 16% (at 95% c.l.) is derived for the photon fraction in cosmic rays with energies above 10{sup 19} eV, based on observations of the depth of shower maximum performed with the hybrid detector of the Pierre Auger Observatory. This is the first such limit on photons obtained by observing the fluorescence light profile of air showers. This upper limit confirms and improves on previous results from the Haverah Park and AGASA surface arrays. Additional data recorded with the Auger surface detectors for a subset of the event sample, support the conclusion that a photon origin of the observed events is not favored.

    The large photomultipliers (PMT) are currently used in astro-particle and neutrino experiments where they have to detect low levels of light. We have studied and characterised large PMTs developed by the PHOTONIS Group Company. The first part of this thesis is dedicated to the full characterization of two types of multipliers currently used in large PMTs. Then, we present results of a new photocathode process, applied on the XPI805 (PMT used in the Pierre Auger Observatory) in order to improve the quantum efficiency. Finally, we study the PMT diameter influence on main parameters (5, 8 and 10 inches). The second part is devoted to the study of the water Cerenkov tank (WCD) response to the shower particles and the horizontal air showers analysis with the Pierre Auger Observatory. The main parameters of a WCD simulation developed in the Auger IPN group were calibrated with several measurements on vertical and inclined muons, performed on dedicated test tanks. The kind of detector used in the surface detector allows detecting very inclined events with a good sensitivity (zenith angle superior to 70 degrees). We have established specific methods to analyze these events (selection and reconstruction). These methods were applied to the Auger data in order to obtain the energy spectrum of the horizontal events. Finally, we detailed two methods to test directly the hadronic models predictions by studying the air showers muonic component. (author)

  19. Obtaining muonic density estimates via application of matrix formalism to proposed surface detector upgrade at the Pierre Auger Observatory

    Event-by-event identification of cosmic ray primary composition lends itself to enhanced event selection in the search for anisotropic arrival directions. Principally, the number of muons reaching Earth's surface in an extensive air shower is indicative of composition. The Pierre Auger Observatory seeks to capitalize on this axiom by improving reconstructed muonic density estimates via an upgrade to its surface detector array. This upgrade, consisting of placing a scintillator on top of each existing water Cherenkov detector, exploits the differing response of two detectors to muonic and electromagnetic particles. Exploitation of this difference may be expressed in a matrix formalism whose application to simulated proton and iron showers is presented here.

  20. Mass production of extensive air showers for the Pierre Auger Collaboration using Grid Technology

    When ultra-high energy cosmic rays enter the atmosphere they interact producing extensive air showers (EAS) which are the objects studied by the Pierre Auger Observatory. The number of particles involved in an EAS at these energies is of the order of billions and the generation of a single simulated EAS requires many hours of computing time with current processors. In addition, the storage space consumed by the output of one simulated EAS is very high. Therefore we have to make use of Grid resources to be able to generate sufficient quantities of showers for our physics studies in reasonable time periods. We have developed a set of highly automated scripts written in common software scripting languages in order to deal with the high number of jobs which we have to submit regularly to the Grid. In spite of the low number of sites supporting our Virtual Organization (VO) we have reached the top spot on CPU consumption among non LHC (Large Hadron Collider) VOs within EGI (European Grid Infrastructure).

    Naphthalene was nitrated with a variety of nitrating agents. Comparison of data with Perrin's electrochemical nitration [Perrin, C. L. (1977) J. Am. Chem. Soc. 99, 5516-5518] shows that nitration of naphthalene gives an α-nitronaphthalene to β-nitronaphthalene ratio that varies between 9 and 29 and is thus not constant. Perrin's data, therefore, are considered to be inconclusive evidence for the proposed one-electron transfer mechanism for the nitration of naphthalene and other reactive aromatics. Moodie and Schoefield [Hoggett, J. G., Moodie, R. B., Penton, J. R. & Schoefield, K. (1971) Nitration and Aromatic Reactivity (Cambridge Univ. Press, London)], as well as Perrin, independently concluded that, in the general scheme of nitration of reactive aromatics, there is the necessity to introduce into the classical Ingold mechanism an additional step involving a distinct intermediate preceding the formation of the Wheland intermediate (σ complexes). This view coincides with our two-step mechanistic picture [Kuhn, S. J. & Olah, G. A. (1961) J. Am. Chem. Soc. 83, 4564-4571] of the nitronium salt nitration of aromatic hydrocarbons (including benzene and toluene), in which low substrate selectivity but high positional selectivity was found, indicating the independence of substrate from positional selectivity.

    Pierre Bourdieu's writings on the state consist of a series of more or less coherent investigations approaching the state from different angles. His writings on the state may seem to contain internal ambiguities. On the one hand, they argue for an actor-centered approach to the state while......, on the other hand, elaborating the power of the state as an institution transcending these actors. The purpose of this article is to reconstruct Bourdieu's understanding of the state in order to examine if the opposition between these two apparently opposite approaches are in as sharp contention as they first...... appear. The article starts out by discussing how Bourdieu has approached the state through his broader sociological approach and concepts. Afterwards it outlines the state formation processes lying at the foundation of the state's power. Next it focuses on his special emphasis on the actor strategies...

    Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with E ≥ 6 x 10{sup 19} eV by analyzing cosmic rays with energies above E ≥ 5 x 10{sup 18} eVarriving within an angular separation of approximately 15 {sup circle}. We characterize the energy distributions inside these regions by two independent methods, one searching for angular dependence of energy-energy correlations and one searching for collimation of energy along the local system of principal axes of the energy distribution. No significant patterns are found with this analysis. The comparison of these measurements with astrophysical scenarios can therefore be used to obtain constraints on related model parameters such as strength of cosmic-ray deflection and density of point sources.

    Among the analysis techniques by ions beams, the micro ERDA (Elastic Detection Analysis) is an interesting technique which allows the quantitative distribution of the hydrogen in materials. In particular, this analysis has been used for hydride zirconium alloys, with the nuclear microprobe of the Laboratory Pierre Sue. This probe allows the characterization of radioactive materials. The technique principles are recalled and then two examples are provided to illustrate the fuel clad behavior in PWR reactors. (A.L.B.)

    We present the first hybrid measurement of the average muon number in air showers at ultrahigh energies, initiated by cosmic rays with zenith angles between 62° and 80°. The measurement is based on 174 hybrid events recorded simultaneously with the surface detector array and the fluorescence detector of the Pierre Auger Observatory. The muon number for each shower is derived by scaling a simulated reference profile of the lateral muon density distribution at the ground until it fits the data. A 1019 eV shower with a zenith angle of 67°, which arrives at the surface detector array at an altitude of 1450 m above sea level, contains on average (2.68 ±0.04 ±0.48 (sys))×107 muons with energies larger than 0.3 GeV. The logarithmic gain d ln Nμ/d ln E of muons with increasing energy between 4 ×1018 eV and 5 ×1019 eV is measured to be (1.029 ±0.024 ±0.030 (sys)) .

    AMIGA (Auger Muons and Infill for the Ground Array) is an upgrade of the Pierre Auger Observatory designed to extend its energy range of detection and to directly measure the muon content of the cosmic ray primary particle showers. The array will be formed by an infill of surface water-Cherenkov detectors associated with buried scintillation counters employed for muon counting. Each counter is composed of three scintillation modules, with a 10 m2 detection area per module. In this paper, a new generation of detectors, replacing the current multi-pixel photomultiplier tube (PMT) with silicon photo sensors (aka. SiPMs), is proposed. The selection of the new device and its front-end electronics is explained. A method to calibrate the counting system that ensures the performance of the detector is detailed. This method has the advantage of being able to be carried out in a remote place such as the one where the detectors are deployed. High efficiency results, i.e. 98% efficiency for the highest tested overvoltage, combined with a low probability of accidental counting (~2%), show a promising performance for this new system.

    The paper describes the new design of the first level trigger for the surface array in the Pierre Auger Observatory. The previous design was tested in a small test segment called Engineering Array (EA). It confirmed full functionality and reliability of the PLD approach. However, because of the high price of the chips available at that time, a new cost-effective design was developed. Altera ( R) offered cost-effective family, which allows reducing the total budget of the electronics without compromise in the functionality. The here described concept of a splitting of data processing into two sub-channels implemented into the parallel working chips, the chips synchronization and the automatization of internal processing management, together with the fully pipelined AHDL code became the framework for the further implementation in the environmental condition of the Argentinian pampa

    The workup of patients with Pierre Robin sequence (PRS) consists of a physical examination, O 2 saturation, and polysomnography to determine the severity of respiratory obstruction and need for surgery. We suggest that capillary blood gas (CBG) may be a better physiologic representation of airway obstruction and should be routinely used in the management of patients with PRS. This is a multicenter study based on a retrospective review of medical records. The study was performed at tertiary care centers. Patients with PRS <1 year old underwent mandibular distraction osteogenesis. Using successful treatment outcome as a reference standard, receiver operating characteristic (ROC) curve was used to determine the accuracy of the diagnostic test and values for the best sensitivity and specificity to determine the need for surgical intervention. Of 73 patients, 48 had sporadic PRS, 23 had syndromes, 2 had micrognathia, not otherwise specified. Mandibular distraction osteogenesis was performed in 62 patients at a mean age of 39 days. The mean initial Apnea-Hypopnea Index (AHI) in nonsurgical versus surgical groups was 10 versus 31 ( P = .063), pH 7.41 versus 7.34 ( P = .003), pCO 2 43 versus 56 ( P < .001), and HCO 3 27 versus 30 ( P = .022). The ROC curve showed that pCO 2 of 49.5 has the best specificity (100%) and sensitivity (72.6%) profile in terms of need for definitive airway. A simple CBG heel stick may better predict the physiologic effects of obstructive apnea; therefore, it should be added to the algorithm of PRS workup.

  18. Evolution of Evaluation and Assessment in Diverse Audiences in the Digital Age

    Eriksson, S. C.

    2015-12-01

    Over the past decades, researchers have learned more about how people think and act and about the social and political aspects of teaching and learning. This understanding has brought changes in researchers' and practitioners' interactions with diverse groups and individuals. This paper addresses evaluation, a process that measures the degree to which learning and project goals are met and factors contributing to or hindering outcomes. Parallels are drawn to learning assessment. The concepts of inclusion, participation, and constructivism (Mertens, 1999; Mertens and Hopson, 2006) now drive best evaluation practices for projects with persons with disabilities (AEA, 2011). This is also true in cases of other people who have been marginalized in STEM fields, e.g. women and underrepresented groups. Inclusion of these stakeholders has important implications for the validity of an evaluation, including the accuracy of results (Jacobson et al, 2012; Gill, 1999; Lee, 1999). The American Indian Higher Education Consortium's framework for indigenous groups incorporates their values and goals into evaluation design and implementation. It is feasible to include participant input in designing the questions and methods of obtaining data, ensuring that issues of access, opportunity, and power (Shuffelbeam, 2001) are taken into consideration. Geoscience projects with u-learning and m-learning provide opportunities to test these theoretical models in innovative programs such as: field work for students with physical disability; underrepresented minority, secondary students using mobile devices in contextualized learning in informal settings; and graduate students using digital maps to enhance traditional field work. This study compares program evaluation methodology of tradition learning with that of programs for diverse groups of students using digital technology.

  20. Mass composition studies of Ultra High Energy cosmic rays through the measurement of the Muon Production Depths at the Pierre Auger Observatory

    Energy Technology Data Exchange (ETDEWEB)

    2014-01-01

    The Pierre Auger Observatory (Auger) in Argentina studies Ultra High Energy Cosmic Rays (UHECRs) physics. The flux of cosmic rays at these energies (above 1018 eV) is very low (less than 100 particle/km2-year) and UHECR properties must be inferred from the measurements of the secondary particles that the cosmic ray primary produces in the atmosphere. These particles cascades are called Extensive Air Showers (EAS) and can be studied at ground by deploying detectors covering large areas. The EAS physics is complex, and the properties of secondary particles depend strongly on the first interaction, which takes place at an energy beyond the ones reached at accelerators. As a consequence, the analysis of UHECRs is subject to large uncertainties and hence many of their properties, in particular their composition, are still unclear. Two complementary techniques are used at Auger to detect EAS initiated by UHE- CRs: a 3000 km2 surface detector (SD) array of water Cherenkov tanks which samples particles at ground level and fluorescence detectors (FD) which collect the ultraviolet light emitted by the de-excitation of nitrogen nuclei in the atmosphere, and can operate only in clear, moonless nights. Auger is the largest cosmic rays detector ever built and it provides high-quality data together with unprecedented statistics. The main goal of this thesis is the measurement of UHECR mass composition using data from the SD of the Pierre Auger Observatory. Measuring the cosmic ray composition at the highest energies is of fundamental importance from the astrophysical point of view, since it could discriminate between different scenarios of origin and propagation of cosmic rays. Moreover, mass composition studies are of utmost importance for particle physics. As a matter of fact, knowing the composition helps in exploring the hadronic interactions at ultra-high energies, inaccessible to present accelerator experiments.

    Pierre Robin sequence (PRS) is an important subgroup of cleft palate. We report several lines of evidence for the existence of a 17q24 locus underlying PRS, including linkage analysis results, a clustering of translocation breakpoints 1.06-1.23 Mb upstream of SOX9, and microdeletions both approximately 1.5 Mb centromeric and approximately 1.5 Mb telomeric of SOX9. We have also identified a heterozygous point mutation in an evolutionarily conserved region of DNA with in vitro and in vivo features of a developmental enhancer. This enhancer is centromeric to the breakpoint cluster and maps within one of the microdeletion regions. The mutation abrogates the in vitro enhancer function and alters binding of the transcription factor MSX1 as compared to the wild-type sequence. In the developing mouse mandible, the 3-Mb region bounded by the microdeletions shows a regionally specific chromatin decompaction in cells expressing Sox9. Some cases of PRS may thus result from developmental misexpression of SOX9 due to disruption of very-long-range cis-regulatory elements.

  2. Surgical Management of Pierre Robin Sequence: Using Mandibular Distraction Osteogenesis to Address Hypoventilation and Failure to Thrive in Infancy.

    2016-04-01

    Mandibular hypoplasia may present in isolation or in the context of glossoptosis and a U-shaped, incomplete cleft palate. This latter triad is referred to as Pierre Robin sequence. Deleterious effects of micrognathia that may present during infancy are due primarily to glossoptosis or posterior displacement of the tongue. This tongue base prolapse may cause varying degrees of upper airway obstruction. A surgical option for management of tongue base airway obstruction secondary to mandibular hypoplasia is neonatal mandibular distraction osteogenesis. Herein, the author seeks to outline the benefits and limitations of early mandibular distraction osteogenesis as a way of managing airway obstruction and feeding difficulty in newborns with micrognathia. A description of the author's operative technique as well as potential complications and pitfalls will also be discussed. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    General History of Drugs was first published in 1694 by Pierre Pomet, as a big in-folio volume, illustrated by more than 400 engraved figures. It was a very expensive book. In 1698-1699, just after the publication of the Universal Treaty on Simple Drugs by Lemery, Pomet prepared a new edition in-8°, less expensive. Unfortunately, it was not ready for publication when Pomet died in 1699. Only 208 pages were preprint, but together with manuscript mentions written on the exemplar gathered by BIU Santé, pôle Pharmacie, they were sufficient to prove that Pomet deeply felt that Lemery had committed plagiarism, copying even some errors he had included in his first edition.

    Full Text Available Este artigo procura contribuir para as discussões em torno do conceito histórico de educação integral, tendo em vista que existem algumas lacunas em torno desse tema. Aqui iremos abordar os conceitos de educação integral no pensamento dos intelectuais: Claude-Henri de Rouvroy ou Conde de Saint-Simon (1760-1825, François Marie Charles Fourier (1772-1837 e Pierre-Joseph Proudhon (1809-1865. A pesquisa utiliza as obras dos autores escritas/publicadas no século XIX. A metodologia procura entender a produção intelectual de maneira dialética e dentro do contexto histórico em que foi produzida. Indicamos como conclusões que Proudhon, Saint-Simon e Charles Fourier, consideravam no processo educacional que a parte literária estaria diretamente vinculada com a científica, unindo teoria e prática. Podemos aventar que as contribuições desses pensadores foram importante nas reflexões educacionais e na defesa de uma educação comprometida com a transformação social presente no pensamento socialista e no movimento operário do século XIX e XX.

    While docking at the QIT facility at Havre St. Pierre, Quebec, on March 23, 1999, the cargo ship M/V Gordon C. Leitch collided with the dock, ruptured a fuel tank, and spilled 49 metric tons of light bunker oil (IFO-180) in the Gulf of St. Lawrence. The situation seemed under control at the beginning since the ice cover contained the migration of oil, but it quickly degenerated when the whole picture became clear. The spill occurred in a remote location where wildlife is abundant and diversified. The economy was largely dependant on ecotourism and several environmental and social factors had to be considered when devising the clean up procedure. Oil was found on 120 km of shoreline in the vicinity of the Mingan Archipelago National Park, a wildlife sanctuary protected by the government of Canada. There were oil-covered birds, a native hunting ground, several fishing zones and the National Park. The spill was cleaned up in two months. The authors described the different factors to be considered and the appropriateness and effectiveness of the Regional Environmental Emergency Team in setting priorities and choosing the best course of action to deal with each set of circumstances. 1 tab., 2 figs.

    Full Text Available L’évolution mondiale des activités extractives est de plus en plus dépendante de la demande des pays émergents. Les conséquences de la croissance de ces pays sur les exploitations de pierres précieuses sont complexes car le marché des gemmes a de nombreuses particularités. La demande est étroitement liée aux matrices socioculturelles de chaque pays. Par ailleurs, l’enrichissement des populations a également un impact sur la production de pierres telles que les saphirs ou les rubis. En effet, ces gemmes sont principalement extraites dans des exploitations informelles et cette activité est de moins en moins attractive pour une population dont le niveau de vie s’élève peu à peu. Dans les vastes gisements sri lankais et birmans, l’épuisement de la ressource est une autre menace. Finalement, si la croissance du marché du diamant est assurée par le Canada, la Russie et l’Australie, pour les autres gemmes, l’Afrique de l’Est est devenue le nouvel « Eldorado ». Dans ces pays, les contextes géologiques, économiques, politiques et sociaux sont très favorables au développement des exploitations artisanales de gemmes.Extraction activities evolution is more and more dependent on the increase of demand in the emerging countries. The consequences of this growth on the gemstone mining activities are complex. The gemstone market is very special and the demand depends on the historic and cultural situation of every country. Moreover, for precious stones like rubby and sapphire, the supply coming from this emerging country is also affected by the social and economic changes. As the small scale mining is widely held in this activity, people that are becoming richer are less interested in that kind of job. In Sri Lanka and Burma, the depletion of many deposits is an other challenge. Finally, if new diamonds deposits of Canada, Russia and Australia are supplying the growth of the diamond market, Est Africa looks like the new

    Pierre Papon provides an analysis here of Jean-Pierre Pharabod and Gerard Klein's book Heurs et malheurs de la physique quantique [Joys and Woes of Quantum Physics] while, at the same time, giving us a remarkably clear and informative text on developments in quantum physics, telling us what it is, how it overturns hitherto dominant conceptions in physics and our ideas about the universe, and how it may lead to important technological change in the future. Though his text may seem tough going to those of our readers with no scientific back ground, it provides a wealth of information, including for those concerned with forecasting and foresight studies. They will discover how, in the absence of absolute determinism, any simulation of the future of systems, including in the hard sciences, involves a degree of randomness and uncertainty, and they will find how far we really are from simple causal relations of the kind that econometric models often rely upon. Papon's review explains how quantum physics throws the laws of classical physics into question, while setting out the 'incredible truths' it reveals, which may be a source of major scientific and technical developments in years to come

    After being appointed "premier physician" in 1731, Pierre Chirac, thanks to his influence with the king, tried to realize an ambitious project. Inspired by the creation of an Academie de Chirurgie by the "premier surgeon", Chirac decided to creation an Académie de Médecine in Paris. Under his guidance, it was planned to collect opinions from all doctors of the kingdom in order to enhance global knowledge of disease, symptoms and treatments. However, threatened with the loss of its secular superiority, the Paris University Medical School immediately opposed the project. Although well advanced, the project was finally abandoned on Chirac's death.

This is an interpretation which permits to face such matters from inside a fully Surrealist point of view, rather than from outside it (and a little more metaphysically as Juan Larrea pretended to, thus allowing to put the basis for a possible comparison between him and his friend Mabille, who both never failed to influence each other.Keywords: Monism; Surrealism; Materialism; Engels; Marxism.ITQuesto testo è un breve commento dell’articolo Del nuevo mundo di Pierre Mabille, apparso in Messico nel 1943 e che qui forniamo nella nostra traduzione, probabilmente la prima in assoluto in Italia di uno scritto di quest’importante surrealista, poco studiato anche dalla critica francese.Nei limiti dello spazio disponibile e delle tematiche del testo in questione abbiamo preferito esporre le rela¬zioni implicite – eppure così evidenti – del pensiero di Mabille

    We present a comprehensive study of the influence of the geomagnetic field on the energy estimation of extensive air showers with a zenith angle smaller than 60{sup o}, detected at the Pierre Auger Observatory. The geomagnetic field induces an azimuthal modulation of the estimated energy of cosmic rays up to the {approx} 2% level at large zenith angles. We present a method to account for this modulation of the reconstructed energy. We analyse the effect of the modulation on large scale anisotropy searches in the arrival direction distributions of cosmic rays. At a given energy, the geomagnetic effect is shown to induce a pseudo-dipolar pattern at the percent level in the declination distribution that needs to be accounted for. In this work, we have identified and quantified a systematic uncertainty affecting the energy determination of cosmic rays detected by the surface detector array of the Pierre Auger Observatory. This systematic uncertainty, induced by the influence of the geomagnetic field on the shower development, has a strength which depends on both the zenith and the azimuthal angles. Consequently, we have shown that it induces distortions of the estimated cosmic ray event rate at a given energy at the percent level in both the azimuthal and the declination distributions, the latter of which mimics an almost dipolar pattern. We have also shown that the induced distortions are already at the level of the statistical uncertainties for a number of events N {approx_equal} 32 000 (we note that the full Auger surface detector array collects about 6500 events per year with energies above 3 EeV). Accounting for these effects is thus essential with regard to the correct interpretation of large scale anisotropy measurements taking explicitly profit from the declination distribution.

Between the two world wars, France reinforced its cultural policy abroad. Many French Institutes were founded, particularly in the coutries of the "Petit Entente" and in Latin America. These institutes were located near foreign universities which helped French Scholars travel abroad. Pierre Deffontaines (1894-1978 is significant in this respect, as most of his carrer took place abroad. Thanks to the two main successive positions which he held - one in France at the Catholic Faculties of Lille (1924-1939, the other in Spain as the director of the French Institute of Barcelona (1939-1964 - he travelled extensively abroad, particularly in the Americas: Brazil, Argentina, Uruguay and Québec. He may have been the French geographer who was the best known abroad and who promoted the largest number of geography departments and associations in various places. As a disciple of Jean Brunhes, he succeeded in associating the promotion of French culture to the promotion of geography.

    Kohlberg and Mertens [Kohlberg, E. & Mertens, J. (1986) Econometrica 54, 1003-1039] proved that the graph of the Nash equilibrium correspondence is homeomorphic to its domain when the domain is the space of payoffs in normal-form games. A counterexample disproves the analog for the equilibrium outcome correspondence over the space of payoffs in extensive-form games, but we prove an analog when the space of behavior strategies is perturbed so that every path in the game tree has nonzero probability. Without such perturbations, the graph is the closure of the union of a finite collection of its subsets, each diffeomorphic to a corresponding path-connected open subset of the space of payoffs. As an application, we construct an algorithm for computing equilibria of an extensive-form game with a perturbed strategy space, and thus approximate equilibria of the unperturbed game.

    This thesis is focused in the development of analysis methods of data measured by the Pierre Auger Observatory's surface array.The Auger Observatory is being built in Malargue, Mendoza and its objective is to detect ultra high energy cosmic rays (E > 10 1 8eV) in order to understand their origin, propagation and to be able to identify their sources.Chapter 1 is a summary of current cosmic rays' theory.It includes details about the energy spectrum of cosmic rays, acceleration sites, forms of acceleration, chemical composition of cosmic rays, the GZK cutoff, magnetic lensing and experiments.Following in Chapter 2 deflection as a function of energy, using the equation of small deflections to first or second order, is analyzed, and the energy range where is approximation is valid is determined.Then, the case of multiple images, which appear when a caustic crosses the position of a source, is studied.Two simulations of cosmic rays from point sources and propagating through a realistic model of the galactic magnetic field were used.Principal and secondary images were analyzed in order to extract information concerning their sources and the magnetic fields they passed through.In Chapter 3 the Minimal Spanning Tree method (MST) used for the detection of filamentary structures is studied.This method was adapted to the analysis of cosmic rays' arrival directions, considering that the detector only observes a part of the sky, with a non uniform exposure and that the density of events depends on exposure.Moreover, the correlation between energy and position is analyzed including now experimental errors in the simulations. Correlated events with experimental errors plus background are simulated and methods of extracting the correlated structure, identifying its source and deducing information about the magnetic field are determined.Finally, conclusions are made, highlighting the most relevant results [es

    Ultra-high-energy cosmic rays (UHECR) are particles of uncertain origin and composition, with energies above 1 EeV (1018 eV or 0.16 J). The measured flux of UHECR is a steeply decreasing function of energy. The largest and most sensitive apparatus built to date to record and study cosmic ray Extensive Air Showers (EAS) is the Pierre Auger Observatory. The Pierre Auger Observatory has produced the largest and finest amount of data ever collected for UHECR. A broad physics program is being carried out covering all relevant topics of the field. Among them, one of the most interesting is the problem related to the estimation of the mass composition of cosmic rays in this energy range. Currently the best measurements of mass are those obtained by studying the longitudinal development of the electromagnetic part of the EAS with the Fluorescence Detector. However, the collected statistics is small, specially at energies above several tens of EeV. Although less precise, the volume of data gathered with the Surface Detector is nearly a factor ten larger than the fluorescence data. So new ways to study composition with data collected at the ground are under investigation. The subject of this thesis follows one of those new lines of research. Using preferentially the time information associated with the muons that reach the ground, we try to build observables related to the composition of the primaries that initiated the EAS. A simple phenomenological model relates the arrival times with the depths in the atmosphere where muons are produced. The experimental confirmation that the distributions of muon production depths (MPD) correlate with the mass of the primary particle has opened the way to a variety of studies, of which this thesis is a continuation, with the aim of enlarging and improving its range of applicability. We revisit the phenomenological model which is at the root of the analysis and discuss a new way to improve some aspects of the model. We carry

Robusta was assessed from planting until the fourth year in both locations and after pruning until the fourth year in Alcarraza. The coffee trees were planted at 3 x 1,5 m in Cambisol under Samanea saman Jerr shade in the first town and Leucaena leucocephala Lam de Wit in the second. The biomass was separated into: leaves, branches, stems, fruits and roots. From 24 months and one year after pruning, leaflitter was collected monthly. For the study of the root system soil blocks of 25 x 25 x 25 cm were extracted, in an area formed by 1,5 m (distance to the street) and 0,75 m (between plants), centered relative to the coffee plant and up to a meter deep. The extracted soil represented ¼ of the volume occupied by the plant. The dry mass of each organ was determined. Dry matter production reached values of 25 t dry mass ha-1 regardless of the stage of the plantation. Until the fourth year the root system dominated the biomass, followed by the leaves and then the stems. The participation of the fruits in the biomass increased in the crop stage and when concluding the experiment the coffees had dedicated for its formation among the 16-20 % of the total dry mass, independently of the development cycle.

    Aaronson, Nicole Leigh; Jabbour, Noel

    2017-09-01

    This study looks to correlate telemetry data gathered on patients with Pierre Robin Sequence (PRS) with sleep study data. Strong correlation might allow obstructive sleep apnea (OSA) to be reasonably predicted without the need for sleep study. Charts from forty-six infants with PRS who presented to our children's hospital between 2005 and 2015 and received a polysomnogram (PSG) prior to surgical intervention were retrospectively reviewed. Correlations and scatterplots were used to compare average daily oxygen nadir, overall oxygen nadir, and average number of daily desaturations from telemetry data with apnea-hypopnea index (AHI) and oxygen nadir on sleep study. Results were also categorized into groups of AHI ≥ or sleep study data. Patients with O2 nadir below 80% on telemetry were not more likely to have an O2 nadir below 80% on sleep study. Patients with an average O2 nadir below 80% did show some correlation with having an AHI greater than 10 on sleep study but this relationship did not reach significance. Of 22 patients who did not have any desaturations on telemetry below 80%, 16 (73%) had an AHI >10 on sleep study. In the workup of infants with PRS, the index of suspicion is high for OSA. In our series, telemetry data was not useful in ruling out severe OSA. Thus our data do not support forgoing sleep study in patients with PRS and concern for OSA despite normal telemetry patterns.

    Pierre-Robin syndrome (PRS) is often associated with difficulty in endotracheal intubation. We present the use of percutaneous dilational tracheotomy (PDT) for airway management of a newborn with PRS and a glossopharyngeal web. A 2-day-old term newborn with PRS and severe obstructive dyspnea was evaluated by the anesthesiology team for airway management. A direct laryngoscopy revealed a glossopharyngeal web extending from the base of the tongue to the posterior pharyngeal wall. The infant was spontaneously breathing through a 2 mm diameter fistula in the center of this web. It was decided that endotracheal intubation was impossible, and a PDT was planned. The trachea of the newborn was cannulated, using a 20 gauge peripheral venous catheter and a 0.71 mm guide wire was introduced through this catheter. Using 5 French, 7 French, 9 French, and 11 French central venous catheter kit dilators, staged tracheotomy stoma dilation was performed. By inserting a size 3.0 tracheotomy cannula, PDT was successfully completed in this newborn. This case describes the successful use of PDT for emergency airway management of a newborn with PRS and glossopharyngeal web.

    We present first results from a trigger based on the discrete cosine transform (DCT) operating in new front-end boards with a Cyclone V E field-programmable gate array (FPGA) deployed in seven test surface detectors in the Pierre Auger Test Array. The patterns of the ADC traces generated by very inclined showers (arriving at 70° to 90° from the vertical) were obtained from the Auger database and from the CORSIKA simulation package supported by the Auger OffLine event reconstruction platform that gives predicted digitized signal profiles. Simulations for many values of the initial cosmic ray angle of arrival, the shower initialization depth in the atmosphere, the type of particle, and its initial energy gave a boundary on the DCT coefficients used for the online pattern recognition in the FPGA. Preliminary results validated the approach used. We recorded several showers triggered by the DCT for 120 Msamples/s and 160 Msamples/s.

    To test the hypothesis that a new orthodontic appliance with a velar extension that shifts the tongue anteriorly would reduce upper airway obstruction in infants with Pierre Robin sequence (PRS). Eleven infants with PRS (median age, 3 days) and an apnea index (AI) >3 were studied. The effect of the new appliance on the AI was compared with that of a conventional appliance without a velar extension by using a crossover study design with random allocation. Compared with baseline (mean AI, 13.8), there was a significant decrease in the AI with the new appliance (3.9; P value appliance (14.8; P = .842). Thus, the relative change in AI was -71% (95% CI, -84--49) for the new appliance and +8% (95% CI, -52-142) for the conventional appliance, which was significantly different (P = .004). No severe adverse effects were observed. This new orthodontic appliance appears to be safe and effective in reducing upper airway obstruction in infants with PRS.

  14. THE FORTUITOUS LATITUDE OF THE PIERRE AUGER OBSERVATORY AND TELESCOPE ARRAY FOR RECONSTRUCTING THE QUADRUPOLE MOMENT

    Determining anisotropies in the arrival directions of cosmic rays at the highest energy is an important task in astrophysics. It is common and useful to partition the sky into spherical harmonics as a measure of anisotropy. The two lowest nontrivial spherical harmonics, the dipole and the quadrupole, are of particular interest, since these distributions encapsulate a dominant single source and a plane of sources, as well as offering relatively high statistics. The best experiments for the detection of ultra high energy cosmic rays currently are all ground-based, with highly nonuniform exposures on the sky resulting from the fixed experimental locations on the Earth. This nonuniform exposure increases the complexity and error in inferring anisotropies. It turns out that there is an optimal latitude for an experiment at which nonuniform exposure does not diminish the inference of the quadrupole moment. We derive the optimal latitude and find that (presumably by a fortuitous coincidence) this optimal latitude runs through the largest cosmic ray experiment, the Pierre Auger Observatory (PAO) in the Southern Hemisphere, and close to the largest cosmic ray experiment in the Northern Hemisphere, the Telescope Array (TA). Consequently, assuming a quadrupole distribution, PAO and TA can reconstruct the cosmic ray quadrupole distribution to a high precision without concern for their partial sky exposure

    Full Text Available Pongamia (Pongamia pinnata (L. Pierre is one of a potential tree species to produce biodiesel. Pongamia-based biodiesel development program is still constrained by the availability of quality and quantity seeds due to the limited of seed sources. The purpose of this research was to identify the morphological diversity of fruits, seeds and seedlings from 5 populations in Java Island. Randomized completely design and randomized block design were used to assess the difference of fruits, seeds and seedlings morphological characteristics among populations. Principal component and hierarchy cluster analysis were used to explain variation pattern among populations. The results showed that the difference of populations was significantly affected by the difference of fruits, seeds, and seedlings morphology of pongamia. Seeds from Carita population showed good quality seed indicators with moisture content of 19.31%, and germination capacity of 74.50%. Sturdiness quotient of the seedling was 10.78. Contribution of genetic factor was higher than environtment factor is relation to the differences of morphological characteristics of fruits, seeds and seedlings of pongamia. Morphological character of the five populations can be divided into 3 groups, i.e. the first group of Batukaras and Kebumen, second group of Alas Purwo and Baluran, and group 3 was Carita.

    Full Text Available The review study focused on Czech translation of Pierre Hadot’s Qu’est-ce que la philosophie antique? is divided into three parts. In the first part the motivation behind the question “what is ancient philosophy?” is considered. On the one hand, Hadot aims to show that usual contemporary understanding of philosophy with its emphasis on discourse and theory does not provide adequate perspective to interpret ancient philosophy in its own right and thus the question on its nature must be asked anew. On the other hand, Hadot sees the core of ancient philosophy in specific praxis, not in theory, and this concept serves as norm for critical revision of the contemporary philosophy. The second part is addressed to the content of the chapters. The study accentuates that Hadot offers not only a description of various ancient philosophical schools and movements, but also presents a certain genealogy of the contemporary understanding of philosophy. The final part is dedicated to brief critical assessment of Hadot’s book and draws several conclusions concerning the institutional character of philosophy with regard to present crisis of humanities from its perspective.

    2009-01-01

    Based on the theoretical and empirical approach of Pierre Bourdieu, a multivariate non-linear method is introduced as an alternative way to analyse the complex relationships between social determinants and health. The analysis is based on face-to-face interviews with 695 randomly selected respondents aged 30 to 59. Variables regarding socio-economic status, life circumstances, lifestyles, health-related behaviour and health were chosen for the analysis. In order to determine whether the respondents can be differentiated and described based on these variables, a non-linear canonical correlation analysis (OVERALS) was performed. The results can be described on three dimensions; Eigenvalues add up to the fit of 1.444, which can be interpreted as approximately 50 % of explained variance. The three-dimensional space illustrates correspondences between variables and provides a framework for interpretation based on latent dimensions, which can be described by age, education, income and gender. Using non-linear canonical correlation analysis, health characteristics can be analysed in conjunction with socio-economic conditions and lifestyles. Based on Bourdieus theoretical approach, the complex correlations between these variables can be more substantially interpreted and presented.

  1. Study of ultra-energetic cosmic rays at the Pierre Auger Observatory from particle detection to anisotropy measurement

    2006-09-01

    The Pierre Auger Observatory, still under construction in Argentina, is designed to study the cosmic rays with energies above a few EeV. The experiment combines two complementary techniques: the fluorescence light detection and the sampling of the shower with an array of detectors at ground, covering a surface of 3000 square kilometers. The calculation of the acceptance of the detector, which is of utmost importance to establish the energy spectrum, has been achieved. The method of computation of the acceptance is simple and reliable. The detection efficiency depends on the nature of primary cosmic rays, allowing to study the cosmic rays composition with the surface detector. The calculation of the cosmic rays energy spectrum has been performed, using different methods to estimate the energy of the events. A cross calibration between the fluorescence and the surface detector provides an estimation of the energy almost independent of hadronic interaction models. The study of large scale anisotropies in the cosmic rays angular distribution provides useful informations about the cosmic rays sources and the conditions of propagation. A new analysis method is presented, allowing to estimate the parameters of an underlying dipolar and quadrupolar anisotropy in the data. The method is applied to a preliminary Auger data set.

    We report a multi-resolution search for anisotropies in the arrival directions of cosmic rays detected at the Pierre Auger Observatory with local zenith angles up to 80(o) and energies in excess of 4 EeV (4 × 1018 eV). This search is conducted by measuring the angular power spectrum and performing a needlet wavelet analysis in two independent energy ranges. Both analyses are complementary since the angular power spectrum achieves a better performance in identifying large-scale patterns while the needlet wavelet analysis, considering the parameters used in this work, presents a higher efficiency in detecting smaller-scale anisotropies, potentially providing directional information on any observed anisotropies. No deviation from isotropy is observed on any angular scale in the energy range between 4 and 8 EeV. Above 8 EeV, an indication for a dipole moment is captured, while no other deviation from isotropy is observed for moments beyond the dipole one. The corresponding p-values obtained after accounting for searches blindly performed at several angular scales, are 1.3 × 10-5 in the case of the angular power spectrum, and 2.5 × 10-3 in the case of the needlet analysis. While these results are consistent with previous reports making use of the same data set, they provide extensions of the previous works through the thorough scans of the angular scales.

    Full Text Available To evaluate a comprehensive scoring system which combines clinical manifestations of Pierre Robin Sequence (PRS including severity of breathing difficulties, body weight and preoperative Cormack-Lehane grade, for its correlation with perioperative PRS airway management decision.Forty PRS children were retrospectively recruited after surgery. Specialists examined all subjects and scored for clinical manifestations (1´ - 4´, weight gain (1´- 4´, dyspnea scores (1´- 4´, and Cormack-Lehane grade (1´- 4´. The correlation of the integrated scores and the necessity of endotracheal intubation or laryngeal mask application were analyzed. In addition, the score correlation with postoperative dyspnea and/or low pulse oxygen saturation (SPO2 levels after extubation was determined.In our study every individual patient had a score from 0´ to 16´, while the higher in the numbers represented higher risk of breathing difficulty. All patients with comprehensive scores 13 points required a laryngeal mask assisted airway management and were considered to have difficult airways. Dyspnea after extubation and postoperative low SPO2 occurred among patients who scored over 10 points.In PRS patients, preoperative weight gaining status and severity of dyspnea in combination with Cormack-Lehane classification provide a scoring system that could help to optimize airway management decisions such as endotracheal intubation or laryngeal mask airway placement and has the potential to predict postoperative dyspnea or low SPO2 levels.

    The Pierre Auger Observatory successfully measures cosmic-ray air-showers at the highest energies by detecting both the fluorescence light produced in the atmosphere and the particle density of the shower at the ground. Nevertheless, this procedure does not allow for a precise measurement of the muon to electron ratio of a single shower. As this quantity is connected to the mass of the primary particle, it allows for a cosmic-ray mass composition measurement. To improve the ability of separating muons from the electromagnetic component, scintillator based detectors will be added to each surface detector station. The basic design will consist of several scintillator bars feeding the produced light into a bundle of wavelength shifting fibers. The light can be detected by photomultipliers (PMTs) or by silicon photomultipliers (SiPMs). The latter benefit from their higher photon detection efficiency and robustness. Due to the smaller area of the SiPMs compared to a PMT, the light detection efficiency of this system strongly depends on the quality of the optical coupling of the fiber bundle to the SiPM. Possible solutions are compared.

    Introduction Pierre Robin sequence (PRS) is characterized by microgenia and retrognathia. Cleft palate and glossoptosis are frequently associated with airway obstruction and difficulty in swallowing. Distraction osteogenesis with micro-distractors has recently been considered as a surgical option during the neonatal age. Case presentation A 6-week-old female with PRS underwent mandibular lengthening in neonatal age. Mandibular osteotomies were performed with the piezoelectric scalpel. Discussion Piezosurgery represents an innovative technique as it offers the maxillofacial surgeon the opportunity to make precise bone cuts without damaging the soft tissue, minimizing the invasiveness of the surgical procedure, and the opportunity of working in a field which is almost totally blood free. Conclusion The use of a piezoelectric device to perform this kind of surgery provides clinical and surgical results which would be difficult with traditional instruments, not only for the patient’s benefit but also for the surgeon’s. Preservation of the original bony structure, especially of the cancellous bone, will benefit the bone healing process due to its high estrogenic potential. PMID:25555147

    Full Text Available El artículo analiza los aportes de la teoría sociológica de Norbert Elías y Pierre Bourdieu al campo de las ciencias sociales. Siguiendo a Corcuff, podemos ubicar las obras de estos dos autores dentro de las teorías constructivistas. Teorías que producen un desplazamiento mismo del objeto de la sociología: ni la sociedad ni los individuos, concebidos como entidades separadas, sino las relaciones entre individuos. Con ello, se abordan el rechazo a la teoría pura; el abordaje multidisciplinar y la vigilancia epistemológica en la construcción del objeto de estudio; la superación de la oposición subjetivismo-objetivismo; la explicación social, histórica y relacional de los fenómenos sociales; la concepción agonista de lo social; y, por último, el eje temático que atraviesa las obras de dos autores con diferencias pero complementarios.

  11. Approaches to the study of religion in Pierre Bourdieu’s social theory

    Full Text Available The article considers Pierre Bourdieu’s approaches to the study of religion: the author analyzes basic concepts of Bourdieu’s sociology of religion and identifies religious spheres and traditions to which his ideas can be applied. The methods developed by Bourdieu, despite their limitations, successfully work in the contemporary studies. Bourdieu’s theory of religion became the starting point for some new approaches, in particular, for the study of ritual practices. His concept of religious habitus allows to analyze the mechanisms by which the religion generates certain practices, conventions, life styles, meanings and values according to its doctrine and experience. Representatives of one denomination usually not only follow the same rules and rituals, but also have a similar taste, life style and perception of religious leaders. The habitus embodies traditions and history of a denomination; it is a means of keeping up practices and their transfer to next generations. At the same time, Bourdieu’s approaches to the study of religion have some weaknesses: his theoretical model is too dependent on the French context and describes mainly the catholic church; his techniques aim to analyze the relationship between the state and the dominant church with its hierarchical structure. Another limitation of Bourdieu’s approach is that he attributes economic logic of supply and demand to the religious activities, and defines religion as determined exclusively to legalize and reproduce unequal and unjust social order. Bourdieu believed that the church was always linked with the mechanisms of social domination, exercise of power and consecration of the ruling classes’ privileges, i.e. with the merits of maintaining social order and legitimizing the power. Thus, Bourdieu credits the producers of religious capital with too much power and capabilities, which they do not really have. In Bourdieu’s theory, religion is an instrument of the struggle

    Full Text Available Ne Il sistema periodico accade che i processi dell’alterazione e del rovesciamento investano le funzioni stesse della narrazione e della testimonianza. In Uranio il personaggio di Bonino, narratore inattendibile, è un doppio rovesciato di Primo Levi. Egli realizza uno degli incubi dello scrittore torinese, quello di raccontare l’esperienza vissuta nel lager e di non essere creduto, ma l’effetto di rovesciamento riguarda anche altri versanti della scrittura. Come Elie Wiesel nel racconto intitolato Barbara, incluso nella raccolta de L’ebreo errante del 1966, Levi prende le distanze, in Uranio, da una memoria che falsifica, che oltrepassa la barriera della verità per costruire un’immagine eroica dei sopravvissuti. Nell’opera di Levi le figure di doppi rovesciati segnalano rischi incombenti, ipotesi inquietanti; i processi di alterazione, invece, si adattano meglio allo sforzo di conoscenza che riguarda l’universo concentrazionario. In questo rapporto stanno il Bonino di Uranio e il Cerrato di Argento, il dottor Müller di Vanadio (ancora ne Il sistema periodico e l’ingegner Mertens del racconto di Auschwitz, città tranquilla (pubblicato nell’84 e aggiunto ai Racconti e saggi. Dietro i nomi di Müller e di Mertens si celano, però, figure in carne e ossa con le quali lo scrittore è entrato in contatto. Il capovolgimento rivela un’ipotesi provocatoria, una vertigine del pensiero, nel caso di Mertens; l’alterazione apre alla conoscenza etica nella vicenda di Müller.The study focuses on the methods of alteration and overturning that influence functions of narration and testimony in Primo Levi’s Il sistema periodico (1975. In the short story Uranio, the character of Bonino is an unreliable storyteller as well as an overturned double of the writer. Bonino represents one of Levi’s obsessions, i.e., not being believed when telling the experience of prison and extermination camps. The effect of overturning also regards

    The overall picture of the highest energy particles produced in the Universe is changing because of measurements made with the Pierre Auger Observatory. Composition studies of cosmic rays point towards an unexpected mixed composition of intermediate mass nuclei, more isotropic than anticipated, which is reshaping the future of the field and underlining the priority to understand composition at the highest energies. The Observatory is competitive in the search for neutrinos of all flavors above about 100 PeV by looking for very inclined showers produced deep in the atmosphere by neutrinos interacting either in the atmosphere or in the Earth's crust. It covers a large field of view between -85° and 60° declination in equatorial coordinates. Neutrinos are expected because of the existence of ultra high energy cosmic rays. They provide valuable complementary information, their fluxes being sensitive to the primary cosmic ray masses and their directions reflecting the source positions. We report the results of the neutrino search providing competitive bounds to neutrino production and strong constraints to a number of production models including cosmogenic neutrinos due to ultra high energy protons. We also report on two recent contributions of the Observatory to multimessenger studies by searching for correlations of neutrinos both with cosmic rays and with gravitational waves. The correlations of the directions of the highest energy astrophysical neutrinos discovered with IceCube with the highest energy cosmic rays detected with the Auger Observatory and the Telescope Array revealed an excess that is not statistically significant and is being monitored. The targeted search for neutrinos correlated with the discovery of the gravitational wave events GW150914 and GW151226 with advanced LIGO has led to the first bounds on the energy emitted by black hole mergers in Ultra-High Energy Neutrinos.

    Full Text Available O objetivo deste ensaio é apontar a produtividade de algumas das formulações de Pierre Bourdieu a respeito da arte e da estética para a viabilização de uma reflexão propriamente antropológica sobre esse tema, situando-o no âmbito de discussões contemporâneas que exploram sua dimensão comparativa. A partir de um paralelo com a teoria da magia de Marcel Mauss, o ensaio estrutura-se em torno de três eixos: identificar a perspectiva que fundamenta o esforço teórico de Bourdieu; mapear alguns de seus principais desdobramentos; verificar sua amplitude teórica. Essa abordagem permite revelar o estatuto metodológico da "distinção" em sua conexão com o relativismo sociológico de Bourdieu, bem como promover uma avaliação crítica do debate contemporâneo a respeito das condições de possibilidade de uma antropologia da arte e/ou da estética nos termos de um contraponto entre particularismo e universalismo.

  20. Infrared quantitative spectroscopy and planetary atmospheres

    Optical measurements of atmospheric minor constituents are carried out using spectrometers working in the UV-visible, infrared and microwave spectral ranges. In all cases the quality of the analysis and of the interpretation of the atmospheric spectra requires the best possible knowledge of the molecular parameters of the species of interest. To illustrate this point we will concentrate on recent laboratory studies of nitric acid, chlorine nitrate and formaldehyde. Nitric acid is one of the important minor constituent of the terrestrial atmosphere. Using new and accurate experimental results concerning the spectroscopic properties of the H14NO3 and H15NO3 molecules, as well as improved theoretical methods (Perrin et al., 2004), it has been possible to generate an improved set of line parameters for these molecules in the 11.2 μm spectral region. These line parameters were used to detect for the first time the H15NO3 molecule in the atmosphere analyzing atmospheric spectra recorded by the MIPAS experiment. The retrievals of chlorine nitrate profiles are usually performed using absorption cross sections (Birk and Wagner, 2003). Following a high resolution analysis of the ν3 and ν4bands of this species in the 12.8 μm region wepropose, as a possibility, to use line by line calculation simulating its ν4Q-branch for the atmospheric temperature and pressure ranges. For the measurement of atmospheric formaldehyde concentrations, mid-infrared and ultraviolet absorptions are both used by ground, air or satellite instruments. It is then of the utmost importance to have consistent spectral parameters in these various spectral domains. Consequently the aim of the study performed at LISA (Gratien et al., 2007) was to intercalibrate formaldehyde spectra in the infrared and ultraviolet regions acquiring simultaneously UV and IR spectra using a common optical cell. The results of the work will be presented. Also high resolution infrared data derived from Perrin et al., 2003

    Defects of long-range regulatory elements of dosage-sensitive genes represent an under-recognized mechanism underlying genetic diseases. Haploinsufficiency of SOX9, the gene essential for development of testes and differentiation of chondrocytes, results in campomelic dysplasia, a skeletal malformation syndrome often associated with sex reversal. Chromosomal rearrangements with breakpoints mapping up to 1.6 Mb up- and downstream to SOX9, and disrupting its distant cis-regulatory elements, have been described in patients with milder forms of campomelic dysplasia, Pierre Robin sequence, and sex reversal. We present an ∼1.58 Mb deletion mapping ∼1.28 Mb upstream to SOX9 that encompasses its putative long-range cis-regulatory element(s) and MAP2K6 in a patient with Pierre Robin sequence and osteopenia with multiple fractures. Low bone mass panel testing using massively parallel sequencing of 23 nuclear genes, including COL1A1 and COL1A2 was negative. Based on the previous mouse model of Map2k6, suggesting that Sox9 is likely a downstream target of the p38 MAPK pathway, and our previous chromosome conformation capture-on-chip (4C) data showing potential interactions between SOX9 promoter and MAP2K6, we hypothesize that deletion of MAP2K6 might have affected SOX9 expression and contributed to our patient's phenotype. © 2015 Wiley Periodicals, Inc.

On peut le « regarder de tous côtés sans déception », selon la définition du peintre chinois Liu Dan donne à propos des rochers qu’il aime à dessiner. Les êtres humains, lancés par un pertuis de chair dans le chaos du monde, acceptent leurs destins collectifs par ces formes en résonnance. Naître au monde, c’est refuser et accepter tout à la fois des contractions et des contradictions mythiques, qui vont nourrir aléatoirement une substance intime. Le nu, le naître et la force des choses sont extraordinairement liés aux lieux de vie et au pouvoir des transformations. Répondre à la question “qui invente les mythes?” est donc un exercice difficile : la vérité est la seule chose que l’on peut inventer, sera ma première réponse. Le mythe répond à une nécessité explicative du monde et sa forme concrète participe d’une énigme pérenne du vivant.

    An in-situ calibration of a logarithmic periodic dipole antenna with a frequency coverage of 30 MHz to 80 MHz is performed. Such antennas are part of a radio station system used for detection of cosmic ray induced air showers at the Engineering Radio Array of the Pierre Auger Observatory, the so-called Auger Engineering Radio Array (AERA) . The directional and frequency characteristics of the broadband antenna are investigated using a remotely piloted aircraft carrying a small transmitting antenna. The antenna sensitivity is described by the vector effective length relating the measured voltage with the electric-field components perpendicular to the incoming signal direction. The horizontal and meridional components are determined with an overall uncertainty of 7.4+0.9-0.3% and 10.3+2.8-1.7% respectively. The measurement is used to correct a simulated response of the frequency and directional response of the antenna. In addition, the influence of the ground conductivity and permittivity on the antenna response is simulated. Both have a negligible influence given the ground conditions measured at the detector site. The overall uncertainties of the vector effective length components result in an uncertainty of 8.8+2.1-1.3% in the square root of the energy fluence for incoming signal directions with zenith angles smaller than 60°.

  4. A measurement of the muon number in showers using inclined events detected at the Pierre Auger Observatory

    Full Text Available The average muon content of measured showers with zenith angles between 62∘ and 80∘ detected at the Pierre Auger Observatory is obtained as a function of shower energy using a reconstruction method specifically designed for inclined showers and the hybrid character of the detector. The reconstruction of inclined showers relies on a comparison between the measured signals at ground and reference patterns at ground level from which an overall normalization factor is obtained. Since inclined showers are dominated by muons this factor gives the relative muon size. It can be calibrated using a subsample of showers simultaneously recorded with the fluorescence detector (FD and the surface detector (SD which provides an independent calorimetric measurement of the energy. The muon size obtained for each shower becomes a measurement of the relative number of muons with respect to the reference distributions. The precision of the measurement is assessed using simulated events which are reconstructed using exactly the same procedure. We compare the relative number of muons versus energy as obtained to simulations. Proton simulations with QGSJETII show a factor of 2.13 ± 0.04(stat ± 0.11(sys at 1019eV without significant variations in the energy range explored between 4 × 1018eV to 7 × 1019eV. We find that none of the current shower models, neither for proton nor for iron primaries, are able to predict as many muons as are observed.

    Full Text Available Malapari (Pongamia pinnata (L. Pierre is an oil-producing plant which has the potential for biodiesel feedstock. This becomes a reason that Malapari plants need to be developed and cultivated. Malapari grow naturally in lowland forests on calcareous soils, rocks on the beach, along the edge of the mangroves and along stream and river tides. This study aims to determine the characteristics of Malapari and relationship between the two accessions grown in North Bali (Pemaron, Uma Anyar, Kalisada, Pengulon, Sumber Kelampok and East Java (Alas Purwo National Park and Baluran National Park based on morphological characters and oil content. The research was conducted in July-November 2015. The method used in this research was observation of morphological characters as well as the analysis of the oil content of seeds.

Scientific research in paleolithic art is trying since more than 20 years to use modern laboritory devises and techniques like the Scanning Electron Microscope and more recently the 3D scanning. For the engraved stones of the site of La Marche have been studied by 3D microtopography as a complementary technique. This non destructif protocole made a new approach of engraving technology and motif composition possible (chronology of the lines, traces morphology etc.. This leads to better understanging of the techniques and gestures used by prehistoric artists. Moreover studies of this type can give more informations obout the function and the history of the stones in a prehistoric rockshelter and by this way the role of theses stones in the life of the magdaleanian hunter-gatherer communities.

  7. Propagation and sky distribution of ultra-high energy cosmic rays; Propagation et distribution sur le ciel des rayons cosmiques d'ultra-haute energie dans le cadre de l'Observatoire Pierre Auger

    The origin of ultra-high energy cosmic rays remains an enigma of modern physics, which the Pierre Auger Observatory, a detector with a hybrid detection mode and an unprecedented size, will try to solve. The direct observation of the sources of those particles, or of large-scale structures in the sky associated to the sources, is one of the main goals of the observatory. Such observations should also allow to constrain cosmic ray propagation between their sources and the Earth, which is complicated by interactions with low-energy photon backgrounds and deflections in astrophysical magnetic fields. This thesis is made of two parts, in order to observe and simulate the sources of cosmic rays within the Auger Observatory. We begin with an extensive description of the Pierre Auger Observatory, and study the acceptance of its surface detector in order to build accurate sky exposure maps, an essential tool in order to study anisotropies. Then we present methods to search for anisotropies in the sky, and analyze the first two years of Auger data. After a description of the phenomena that can influence the propagation and observation of ultrahigh energy cosmic ray sources, we present numerical simulations aiming at predicting observables such as the spectrum, anisotropies and composition measurable by Auger as a function of various astrophysical models. We show that extragalactic magnetic fields can play a crucial role in particular if cosmic rays are partly heavy nuclei. Finally, we show that the propagation of these particles from a nearby source generates secondary fluxes of gamma-rays that could be detected by TeV gamma-ray telescopes. (author)

  8. A Significant Source for the Madeleine and Other Major Episodes in Combray: Proust's Intertextual Use of Pierre Loti's My Brother Yves

    Richard M. Berrong

    2014-01-01

    Full Text Available The most famous passage in Marcel Proust’s In Search of Lost Time , and one of the most famous passages in Western literature, is the moment when the narrator sips tea while eating a shell-shaped pastry called a madeleine and suddenly recalls very vividly an apparently long-forgotten scene from his childhood. From this episode Proust developed his theories about involuntary memory and its important role in our emotional welfare. Proust was an avid reader of the French novelist Pierre Loti when he was young. Contemporary accounts show that he was able to recite whole passages from Loti’s work in public from memory. This article demonstrates the extent to which Proust made intertextual use of scenes from Loti’s novel My Brother Yves in constructing the madeleine and other famous passages in Combray , the first section of In Search of Lost Time. It does not attempt to question the originality of Proust’s work. Rather, building on previous studies of intertextuality in Proust, it seeks to show how the author went about creating his work and dialoguing with at least some of his potential contemporary readers.

    In this paper a comparison between three models for predicting the total solar flux falling on a horizontal surface has been processed. Capderou, Perrin & Brichambaut and Hottel models used to estimate the global solar radiation, the models are identified and evaluated using MATLAB environment. The recorded data have been obtained from a small weather station installed at the LAGE laboratory of Ouargla University, Algeria. Solar radiation data have been recorded using four sample days, every 15thday of the month, (March, April, May and October). The Root Mean Square Error (RMSE), Correlation Coefficient (CC) and Mean Absolute Percentage Error (MAPE) have been also calculated so as that to test the reliability of the proposed models. A comparisons between the measured and the calculated values have been made. The results obtained in this study depict that Perrin & Brichambaut and Capderou models are more effective to estimate the total solar intensity on a horizontal surface for clear sky over Ouargla city (Latitude of 31° 95' N, Longitude of 5° 24' E, and Altitude of 0.141km above Mean Sea Level), these models dedicated from meteorological parameters, geographical location and number of days since the first January. Perrin & Brichambaut and Capderou models give the best tendency with a CC of 0.985-0.999 and 0.932-0.995 consecutively further, Hottel give's a CC of 0.617-0.942.

Study of ultra-energetic cosmic rays at the Pierre Auger Observatory from particle detection to anisotropy measurement; Etude des rayons cosmiques ultra-energetiques avec l'Observatoire de Pierre Auger: de l'acceptance du detecteur a la nature des particules primaires et aux mesures d'anisotropies

    The Pierre Auger Observatory, still under construction in Argentina, is designed to study the cosmic rays with energies above a few EeV. The experiment combines two complementary techniques: the fluorescence light detection and the sampling of the shower with an array of detectors at ground, covering a surface of 3000 square kilometers. The calculation of the acceptance of the detector, which is of utmost importance to establish the energy spectrum, has been achieved. The method of computation of the acceptance is simple and reliable. The detection efficiency depends on the nature of primary cosmic rays, allowing to study the cosmic rays composition with the surface detector. The calculation of the cosmic rays energy spectrum has been performed, using different methods to estimate the energy of the events. A cross calibration between the fluorescence and the surface detector provides an estimation of the energy almost independent of hadronic interaction models. The study of large scale anisotropies in the cosmic rays angular distribution provides useful informations about the cosmic rays sources and the conditions of propagation. A new analysis method is presented, allowing to estimate the parameters of an underlying dipolar and quadrupolar anisotropy in the data. The method is applied to a preliminary Auger data set.

    2016-06-01

    Full Text Available Resumo Este artigo propõe uma releitura crítica da contribuição de Pierre Bourdieu para o campo de estudo das religiões. Demonstraremos inicialmente como o conceito de campo alargou a noção clássica de religião. Em seguida, evidenciaremos por que a dimensão estrutural subjacente ao conceito não consegue dar conta de muitas das dimensões do secularismo contemporâneo, em particular o modo como a esfera pública vem sendo modelada pela presença pública das religiões. Finalmente, partindo da contribuição de autores pós-bourdiesianos para uma definição pragmatista da arena pública, tais como Daniel Cefaï e outros, sugerimos deslocar o olhar sobre as religiões em suas relações com o poder, perguntando-nos não tanto o que as religiões fazem na esfera pública, mas, sobretudo, o que a publicidade faz da religião.

    In 1886 Pierre Marie used the term "acromegaly" for the first time and gave a full description of the characteristic clinical picture. However several others had already given clear clinical descriptions before him and sometimes had given the disease other names. After 1886, it gradually became clear that pituitary enlargement (caused by a pituitary adenoma) was the cause and not the consequence of acromegaly, as initially thought. Pituitary adenomas could be found in the great majority of cases. It also became clear that acromegaly and gigantism were the same disease but occurring at different stages of life and not different diseases as initially thought. At the end of the 19th and beginning of the 20th century most information was derived from case descriptions and post-mortem examinations of patients with acromegaly or (famous) patients with gigantism. The stage was set for further research into the pathogenesis, diagnosis and therapy of acromegaly and gigantism.

  15. Measurement of the cosmic ray spectrum above 4 × 10{sup 18} eV using inclined events detected with the Pierre Auger Observatory

    Collaboration: Pierre Augur Collaboration

    2015-08-01

    A measurement of the cosmic-ray spectrum for energies exceeding 4×10{sup 18} eV is presented, which is based on the analysis of showers with zenith angles greater than 60° detected with the Pierre Auger Observatory between 1 January 2004 and 31 December 2013. The measured spectrum confirms a flux suppression at the highest energies. Above 5.3×10{sup 18} eV, the ''ankle'', the flux can be described by a power law E{sup −γ} with index γ=2.70 ± 0.02 (stat) ± 0.1 (sys) followed by a smooth suppression region. For the energy (E{sub s}) at which the spectral flux has fallen to one-half of its extrapolated value in the absence of suppression, we find E{sub s}=(5.12±0.25 (stat){sup +1.0}{sub −1.2} (sys))×10{sup 19} eV.

  17. Search for first harmonic modulation in the right ascension distribution of cosmic rays detected at the Pierre Auger Observatory

    2011-01-01

    Full text: The large-scale distribution of the arrival directions of Ultra-High Energy Cosmic Rays (UHECRs) is, together with the spectrum and the mass composition, an important observable in attempts to understand their nature and origin. In this work we show the results of searches for dipolar-type anisotropies in different energy ranges above 2.5 x 10 17 eV with the surface detector array of the Pierre Auger Observatory. For events with energy above 1 EeV we present searches for first harmonic modulations in right-ascension based on the classical Rayleigh analysis slightly modified to account for the small variations of the exposure. The results for events with energy below 1 EeV are derived using simple event counting rate differences between Eastward and Westward directions in order to take into account the detector-dependent variations in the counting rate because in this range of energy the detection efficiency of the array depends on zenith angle and composition. Using relative rates, this technique allows a search for anisotropy in right ascension without requiring any evaluation of the detection efficiency. Upper limits on the amplitudes are obtained, which provide the most stringent bounds at present, being below 2% at 99% C.L. for EeV energies. We also compare our results to those of previous experiments as well as with some theoretical expectations. (author)

  18. The use of Pierre Bourdieu's distinction concepts in scientific articles studying food and eating: A narrative review.

    This article reviews and discusses scientific papers on eating practices that have used Pierre Bourdieu's concepts presented in Distinction: A Social Critique of the Judgement of Taste. It aims to synthesize and analyze theoretical and empirical studies on the theme in order to present Bourdieu's contributions to the field, advances in his theories, and directions for future research. Exclusion criteria were: not written in Portuguese, English, Spanish, or French; not published in a peer-reviewed journal; not analyzing food or eating; and not using Bourdieu's concepts as presented in Distinction as the main theoretical framework. In this narrative review, we found 38 articles, which were categorized main themes: food choice and provisioning, taste, social class, food symbolism, the body, and the scientific field of food and eating. The taste of luxury and the taste of necessity were broadly applied on the works found in this review and were observed among the lower and upper classes, manifesting differently in each class. These studies show that while Bourdieu's theories are still highly relevant to understanding contemporary social groups, they may be improved when combined with other frameworks and theorists. We highlight as directions for future research manners in which gender and the environment interact with the habitus and food choices. Finally, this review points to new areas of investigation that may help improve the use of Bourdieu's concepts in exploring health inequalities, such as differences in eating practices and habitus within populations with low socioeconomic status.

    Usando como hilo conductor la recuperación y superación del legado matemático -y científico- griego, se analizarán en esta colaboración cuatro importantes efemérides matemáticas: la muerte de Thābit ibn Qurra (901, los nacimientos de Gerolamo Cardano (1501 y Pierre de Fermat (1601 y la publicación de las Disquisitiones Arithmeticae de Karl F. Gauss (1801. Con esta perspectiva, consideraremos las contribuciones de Thābit al primer renacimiento de la ciencia y filosofía griegas que se produjo a partir del siglo VIH de manos de los árabes. Gerolamo Cardano aparecerá como actor de otro Renacimiento -este lo solemos escribir con mayúscula-: el italiano; que en este caso culminó con la recuperación para la Europa Occidental de la matemática, filosofía y ciencia griegas, además del arte. La figura de Pierre de Fermat se mostrará decisiva en la creación durante el siglo XVII de las dos herramientas matemáticas que suponen, tras dos mil años de historia, la superación conceptual y operativa de la matemática griega: la geometría analítica y el cálculo diferencial. Aunque en otra medida que Thābit, Cardano y Fermat, las Disquisitiones también pueden conectarse con el espíritu del mundo griego; fue, de hecho, el mismo Gauss quien lo invocó para darle realce y significado a uno de los principales resultados de su libro -el estudio de los polígonos regulares que admiten ser construidos con regla y compás-: «Es ciertamente atónito que nada nuevo se haya añadido a esta teoría desde los tiempos de Euclides hace ya 2.000 años».

    The history of cosmic rays started in the beginning of the 20th century. Since then one of the main questions is their origin. Due to the very low flux at the highest energies huge areas have to be instrumented to answer this question. For this purpose the distribution of the arrival directions of cosmic rays is studied. The largest experiment so far is the Pierre Auger Observatory, located in the Pampa in western Argentina with an area of about 3000 km{sup 2}. In recent years it provided many major contributions to the field of cosmic ray physics and its data is the basis of this work. Among other things a correlation analysis of Ultra High Energy Cosmic Rays (UHECRs) with Active Galactic Nuclei (AGN) was performed leading to the first evidence that UHECRs are not isotropically distributed. Here the distribution of arrival directions of cosmic rays at the highest energies (>50 EeV) is examined by using autocorrelation methods to check whether it is compatible with the isotropic expectation or not.This thesis is organised as follows: in the first two chapters a short introduction to the topic is given, followed by a more general discussion on cosmic rays including models of acceleration, possible sources and the propagation of UHECRs in the third chapter. The fourth chapter focuses on the detector design of the Pierre Auger Observatory and event reconstruction at highest energies.

    We have conducted three searches for correlations between ultra-high energy cosmic rays detected by the Telescope Array and the Pierre Auger Observatory, and high-energy neutrino candidate events from IceCube. Two cross-correlation analyses with UHECRs are done: one with 39 cascades from the IceCube `high-energy starting events' sample and the other with 16 high-energy `track events'. The angular separation between the arrival directions of neutrinos and UHECRs is scanned over. The same events are also used in a separate search using a maximum likelihood approach, after the neutrino arrival directions are stacked. To estimate the significance we assume UHECR magnetic deflections to be inversely proportional to their energy, with values $3^\\circ$, $6^\\circ$ and $9^\\circ$ at 100 EeV to allow for the uncertainties on the magnetic field strength and UHECR charge. A similar analysis is performed on stacked UHECR arrival directions and the IceCube sample of through-going muon track events which were optimized for neutrino point-source searches.

Para tanto, serão apresentados os caminhos traçados pelos autores para pensar a agência humana, através de uma teoria disposicional da ação, que enfatiza os habitus de classe ou as disposições individuais. Por fim, discutiremos os avanços e limites observados nessas perspectivas na apreensão de questões centrais da teoria social contemporânea, como a capacidade reflexiva dos atores e seu papel na reprodução/transformação do mundo social. Essa análise permite questionar em que medida os autores conseguem superar as referidas dicotomias, uma vez que terminam por enfatizar o peso do social sobre as condutas individuais.

    Simultaneous determination of non-fluorescent glycols in mixtures without separation or chemical transformation steps is described. Two methods based in the measure of fluorescence anisotropy of a probe such as fluorescein dissolved in the analyte or analyte mixtures are described. In the first method, the anisotropy spectra of pure and mixtures of analytes are used to quantitative determination (if the fluorophor concentration is in a range where fluorescence intensity is proportional to concentration). In the second method, a calibration curve anisotropy-concentration based on the application of the Perrin equation is established. The methods presented here are capable of directly resolving binary mixtures of non-fluorescent glycols on the basis of differences on the fluorescence anisotropy of a fluorescence tracer. Best analytical performances were obtained by application of the method based on Perrin equation. This method is simple, rapid and allows the determination of mixtures of glycols with reasonable accuracy and precision. Detection limits are limited by the quantum yield and anisotropy values of the tracer in the solvents. Recovery values are related to the differences in anisotropy values of the tracer in the pure solvents. Mixtures of glycerine/ethylene glycol (GL/EG), ethylene glycol/1,2-propane diol (EG/1,2-PPD) and polyethylene glycol 400/1,2-propane diol (PEG 400/1,2-PPD) were analysed and recovery values are within 95-120% in the Perrin method. Relative standard deviation are in the range 1.3-2.9% and detection limits in the range 3.9-8.9%

    Full Text Available Ricinodendron heudelotii (Baill. Pierre ex Pax. kernel (njansang commercialization has been promoted by the World Agroforestry Centre (ICRAF in project villages in Cameroon with the aim to alleviate poverty for small-scale farmers. We evaluated to what extent development interventions improved the financial situation of households by comparing project and control households. The financial importance of njansang to household livelihoods between 2005 and 2010 was investigated through semi-structured questionnaires with retrospective questions, focus group discussions, interviews and wealth-ranking exercises. The importance of njansang increased strongly in the entire study region and the increase was significantly larger in project households. Moreover, absolute numbers of income from njansang commercialization as well as relative importance of njansang in total cash income, increased significantly more in project households (p < 0.05. Although the lower wealth class households could increase their income through njansang trade, the upper wealth class households benefited more from the projects' interventions. Group sales as conducted in project villages did not lead to significantly higher prices and should be reconsidered. Hence, promotion of njansang had a positive effect on total cash income and can still be improved. The corporative actors for njansang commercialization are encouraged to adapt their strategies to ensure that also the lower wealth class households benefit from the conducted project interventions. In this respect, frequent project monitoring and impact analysis are important tools to accomplish this adaptation.

    A search for ultra-high energy photons with energies above 1 EeV is performed using nine years of data collected by the Pierre Auger Observatory in hybrid operation mode. An unprecedented separation power between photon and hadron primaries is achieved by combining measurements of the longitudinal air-shower development with the particle content at ground measured by the fluorescence and surface detectors, respectively. Only three photon candidates at energies 1–2 EeV are found, which is compatible with the expected hadron-induced background. Upper limits on the integral flux of ultra-high energy photons of 0.027, 0.009, 0.008, 0.008 and 0.007 km{sup −2} sr{sup −1} yr{sup −1} are derived at 95% C.L. for energy thresholds of 1, 2, 3, 5 and 10 EeV. These limits bound the fractions of photons in the all-particle integral flux below 0.1%, 0.15%, 0.33%, 0.85% and 2.7%. For the first time the photon fraction at EeV energies is constrained at the sub-percent level. The improved limits are below the flux of diffuse photons predicted by some astrophysical scenarios for cosmogenic photon production. The new results rule-out the early top-down models − in which ultra-high energy cosmic rays are produced by, e.g., the decay of super-massive particles − and challenge the most recent super-heavy dark matter models.

    The paper presents the first results from the trigger based on the Discrete Cosine Transform (DCT) operating in the new Front-End Boards with Cyclone V FPGA deployed in 8 test surface detectors in the Pierre Auger Engineering Array. The patterns of the ADC traces generated by very inclined showers were obtained from the Auger database and from the CORSIKA simulation package supported next by Offline reconstruction Auger platform which gives a predicted digitized signal profiles. Simulations for many variants of the initial angle of shower, initialization depth in the atmosphere, type of particle and its initial energy gave a boundary of the DCT coefficients used next for the on-line pattern recognition in the FPGA. Preliminary results have proven a right approach. We registered several showers triggered by the DCT for 120 MSps and 160 MSps. (authors)

  1. A New Economic and Political State of Play in the Energy Sector: On Jean-Pierre Hansen and Jacques Percebois, Energy. Economy and politics

    Lesourne, J.

    2011-01-01

    If there is one sector in which the state of play has changed radically over a few decades, it is the energy sector. It has been affected simultaneously by the prospect that the main fossil fuels will become exhausted, by the impact on our planet's climate of the consumption of this fossil energy (implying increased recourse to renewable sources) and by the rapid economic development of large nations consuming increasing quantities of energy. Energy-related policies (particularly economic and technological policies) are, in fact, being developed in an increasingly complex and international context, which is, at times, very difficult to grasp. Fortunately, two specialists in energy matters, Jean-Pierre Hansen and Jacques Percebois, have published a very comprehensive survey of this new economic and political state of play in the energy field: 'Energie. Economie et politiques' [Energy: Economics and Policies] (Brussels: De Boeck, 2010). It clearly is not possible here to go into all the questions they confront, but in this review Jacques Lesourne, who has read the book for Futuribles, clearly demonstrates its importance and presents the reader with the main facets of the work that make it a reference tool for all involved in this sector, including the most highly specialized.

  3. Searches for Large-Scale Anisotropy in the Arrival Directions of Cosmic Rays Detected above Energy of $10^{19}$ eV at the Pierre Auger Observatory and the Telescope Array

    Spherical harmonic moments are well-suited for capturing anisotropy at any scale in the flux of cosmic rays. An unambiguous measurement of the full set of spherical harmonic coefficients requires full-sky coverage. This can be achieved by combining data from observatories located in both the northern and southern hemispheres. To this end, a joint analysis using data recorded at the Telescope Array and the Pierre Auger Observatory above 1019 eV is presented in this work. The resulting multipolar expansion of the flux of cosmic rays allows us to perform a series of anisotropy searches, and in particular to report on the angular power spectrum of cosmic rays above 1019 eV. No significant deviation from isotropic expectations is found throughout the analyses performed. Upper limits on the amplitudes of the dipole and quadrupole moments are derived as a function of the direction in the sky, varying between 7% and 13% for the dipole and between 7% and 10% for a symmetric quadrupole.

    Although other researchers had previously observed the random motion of pollen grains suspended in water through a microscope, Robert Brown's name is associated with this behaviour based on observations he made in 1828. It was not until Einstein's work in the early 1900s however, that the origin of this irregular motion was established to be the result of collisions with molecules which were so small as to be invisible in a light microscope (Einstein A 1965 Investigations on the Theory of the Brownian Movement ed R Furth (New York: Dover) (transl. Cowper A D) (5 papers)). Jean Perrin in 1908 (Perrin J 1923 Atoms (New York: Van Nostrand-Reinhold) (transl. Hammick D)) was able, through a series of painstaking experiments, to establish the validity of Einstein's equation. We describe here the details of a junior level undergraduate physics laboratory experiment where students used a microscope, a video camera and video capture software to verify Einstein's famous calculation of 1905.

  12. Jean-Pierre Falret e a definição do método clínico em psiquiatria

    Directory of Open Access Journals (Sweden)

    Fernando A. da Cunha Ramos

    2010-06-01

    Full Text Available Jean-Pierre Falret pode ser considerado a terceira grande figura da medicina mental francesa da primeira metade do século XIX, tendo sido aquele que, após Pinel e Esquirol, foi responsável por dar o acabamento final à obra de fundação da psiquiatria clínica e da patologia mental. A vida de Falret coincide no tempo com o período de domínio cultural e político da França no Ocidente, no qual também a medicina mental francesa se desenvolveu e alcançou seu ápice. Após a morte de Falret, a psiquiatria francesa entra em um lento processo de decadência, sendo sua liderança gradualmente substituída pela da escola psiquiátrica germânica, a qual, ao final do século XIX e início do século XX, dará desenvolvimento a muitas das idéias desse autor. O capítulo introdutório de sua principal obra, Des maladies mentales et des asiles d'aliénés, publicada ao final de sua vida, é considerado, ele próprio, uma obra-prima. Nele, Falret faz a síntese de sua carreira intelectual e clínica, realizando um trabalho de crítica e revisão de inúmeros conceitos da medicina mental da época. Entre as grandes contribuições de Falret, está a definição precisa do método clínico em psiquiatria, com seus três principais aspectos: o enquadre dialético, a perspectiva evolutiva e a supremacia do sujeito psíquico.

Bark extract tested against a set of bacterial and fungal strains also revealed the strongest antimicrobial activity with the largest inhibition zone and lowest minimum inhibitory concentration (MIC. HPLC analysis of aqueous methanol extracts from bark, leaves and seeds indicated the presence of protocatechuic, ellagic, ferulic, gallic, gentisic, 4-hydroxybenzoic and 4-hydroxycinnamic acids in bark (1.50–6.70 mg/100 g DW; sorbic, ferulic, gallic, salicylic and p-coumaric acids in leaves (1.18–4.71 mg/100 g DW; vanillic, gallic and tannic acids in seeds (0.52–0.65 mg/100 g DW as the main phenolic acids. The present investigation concludes that the tested parts of P. pinnata, in particular the bark, have strong potential for the isolation of antioxidant and antimicrobial agents for functional food and pharmaceutical uses.

    Kirill A. Chekalov

    2017-12-01

    Full Text Available The essay examines the structure of a 32-volume series of Fantômas novels created by Pierre Souvestre and Marcel Allain; it traces the origins and development of the serial genre and generic novelties related to seriality. The latter include a relative autonomy of each story in each volume and interconnection of the volumes via the figure of the criminal “slipping away” from the hands of justice. The study compares poetological techniques of the fabula development and points out specific features of the Belle époque reality as represented through the introduction of recognizable “cultural signs,” varia- tions of everyday incidents, and newspaper chronicle of criminal events. It also analyzes the image of Fantômas and other recurrent characters of the series (such as Juve, Fan- dor, Hélène, Lady Maud Beltham, etc. The authors examine para-literary features that can be traced in many other different forms such as TV series and graphic novels. They include (1 mythologization of the main character as embodiment of Evil, or a “criminal genius”; (2 confusion of the real and the fictional, verisimilar and extraordinary, horri- ble and comic based on the variations of literary and journalistic clichés; (3 repetition of plot patterns, (4 attempts to guess and to meet reader’s expectations.

    The distribution of arrival directions of cosmic rays is remarkably uniform over the complete spectrum of energies. At large angular scales only tiny deviations from isotropy have been observed and huge statistics are required to quantify the corresponding amplitudes. The measurement of cosmic rays with energies above 10{sup 15} eV is only feasible with large, earthbound observatories: The cosmic ray primary particles initiate cascades of secondary particles in the Earth's atmosphere. Every aspect of the development of these air showers down to the measurement of the resulting particles at ground level needs to be well understood and controlled in order to precisely reconstruct the properties of the primary particle. The development of air showers is subject to systematic distortions caused by the magnetic field of the Earth. Both this and other local effects are capable of inducing false anisotropy into the distribution of arrival directions. In this thesis, the effect of the geomagnetic field on the energy measurement is modelled and quantified; consequently, a correction of the energy estimator is derived. Furthermore, a method is introduced to fit dipolar patterns to the distribution of arrival directions of cosmic rays as observed from the field of view of the surface detector of the Pierre Auger Observatory. After correcting for all relevant local effects the method is applied to data and the parameters of a potentially underlying dipole are determined and evaluated. (orig.)

    The Database of Vascular Plants of Canada or VASCAN (http://data.canadensys.net/vascan) is a comprehensive and curated checklist of all vascular plants reported in Canada, Greenland (Denmark), and Saint Pierre and Miquelon (France). VASCAN was developed at the Université de Montréal Biodiversity Centre and is maintained by a group of editors and contributors. For every core taxon in the checklist (species, subspecies, or variety), VASCAN provides the accepted scientific name, the accepted French and English vernacular names, and their synonyms/alternatives in Canada, as well as the distribution status (native, introduced, ephemeral, excluded, extirpated, doubtful or absent) of the plant for each province or territory, and the habit (tree, shrub, herb and/or vine) of the plant in Canada. For reported hybrids (nothotaxa or hybrid formulas) VASCAN also provides the hybrid parents, except if the parents of the hybrid do not occur in Canada. All taxa are linked to a classification. VASCAN refers to a source for all name, classification and distribution information. All data have been released to the public domain under a CC0 waiver and are available through Canadensys and the Global Biodiversity Information Facility (GBIF). VASCAN is a service to the scientific community and the general public, including administrations, companies, and non-governmental organizations.

  11. A search for anisotropy in the arrival directions of ultra high energy cosmic rays recorded at the Pierre Auger Observatory

    Energy Technology Data Exchange (ETDEWEB)

    Abreu, P.

    2012-01-01

    Observations of cosmic ray arrival directions made with the Pierre Auger Observatory have previously provided evidence of anisotropy at the 99% CL using the correlation of ultra high energy cosmic rays (UHECRs) with objects drawn from the Veron-Cetty Veron catalog. In this paper we report on the use of three catalog independent methods to search for anisotropy. The 2pt-L, 2pt+ and 3pt methods, each giving a different measure of self-clustering in arrival directions, were tested on mock cosmic ray data sets to study the impacts of sample size and magnetic smearing on their results, accounting for both angular and energy resolutions. If the sources of UHECRs follow the same large scale structure as ordinary galaxies in the local Universe and if UHECRs are deflected no more than a few degrees, a study of mock maps suggests that these three methods can efficiently respond to the resulting anisotropy with a P-value = 1.0% or smaller with data sets as few as 100 events. Using data taken from January 1, 2004 to July 31, 2010 we examined the 20, 30, ..., 110 highest energy events with a corresponding minimum energy threshold of about 51 EeV. The minimum P-values found were 13.5% using the 2pt-L method, 1.0% using the 2pt+ method and 1.1% using the 3pt method for the highest 100 energy events. In view of the multiple (correlated) scans performed on the data set, these catalog-independent methods do not yield strong evidence of anisotropy in the highest energy cosmic rays.

  12. Spatio-temporal variations in biomass and mercury concentrations of epiphytic biofilms and their host in a large river wetland (Lake St. Pierre, Qc, Canada)

    Within wetlands, epiphytes and macrophytes play an important role in storage and transfer of metals, through the food web. However, there is a lack of information about spatial and temporal changes in their metal levels, including those of mercury (Hg), a key priority contaminant of aquatic systems. We assessed total mercury (THg) and methylmercury (MeHg) concentrations of epiphyte/macrophyte complexes in Lake St. Pierre, a large fluvial lake of the St. Lawrence River (Québec, Canada). THg and MeHg concentrations were ten fold higher in epiphytes than in macrophytes. THg concentrations in epiphytes linearly decreased as a function of the autotrophic index, suggesting a role of algae in epiphyte Hg accumulation, and % of MeHg in epiphytes reached values as high as 74%. Spatio-temporal variability in THg and MeHg concentrations in epiphytes and macrophytes were influenced by water temperature, available light, host species, water level, dissolved organic carbon and dissolved oxygen. - Highlights: • Epiphytes and macrophytes are sites of Hg accumulation in a large temperate river. • Epiphytic biofilms are ten fold more contaminated than their macrophyte host. • Physico-chemical variables influences Hg levels in epiphytes and macrophytes. • Up to 74% of total Hg is in the methylated form in epiphytes. • Epiphytes, should be included in Hg foodweb modeling. - Epiphytic biofilms are key sites of methylmercury accumulation in large river wetlands

    International Nuclear Information System (INIS)

    2006-01-01

    This document reports the first part of a study which aimed at verifying the relevance of available studies and measurements for the Saint-Pierre ancient mining site and regarding risks related to radioactivity. More specifically, this study aimed at defining the most precisely as possible the perimeter of potential influence of this site for three pollution vectors (water, air, soils) with respect to available studies and in terms of necessary additional studies, at assessing the radiological impact on populations living, working or staying at the neighbourhood of this restored site, and at proposing an evolution of the current survey arrangement in order to make it more adapted and reliable. This first part is dedicated to the analysis of all existing documents in order to define required additional elements (analysis, sampling, surveys, and so on) for a better knowledge of the present radiological status of the studied site. After a presentation of the physical and human characteristics of the site, and of its geological and mineralogical context, and recalled the past mining activities (extraction, processing, wastes, waste rock and tailings), the report proposes an analysis per component: external exposure, radon and dusts, underground waters, surface waters, sediments, aquatic fauna and flora, food products. An assessment and recommendations are formulated. Financial aspects are discussed

  20. A LINE-1 Insertion in DLX6 Is Responsible for Cleft Palate and Mandibular Abnormalities in a Canine Model of Pierre Robin Sequence

    Cleft palate (CP) is one of the most commonly occurring craniofacial birth defects in humans. In order to study cleft palate in a naturally occurring model system, we utilized the Nova Scotia Duck Tolling Retriever (NSDTR) dog breed. Micro-computed tomography analysis of CP NSDTR craniofacial structures revealed that these dogs exhibit defects similar to those observed in a recognizable subgroup of humans with CP: Pierre Robin Sequence (PRS). We refer to this phenotype in NSDTRs as CP1. Individuals with PRS have a triad of birth defects: shortened mandible, posteriorly placed tongue, and cleft palate. A genome-wide association study in 14 CP NSDTRs and 72 unaffected NSDTRs identified a significantly associated region on canine chromosome 14 (24.2 Mb–29.3 Mb; praw = 4.64×10−15). Sequencing of two regional candidate homeobox genes in NSDTRs, distal-less homeobox 5 (DLX5) and distal-less homeobox 6 (DLX6), identified a 2.1 kb LINE-1 insertion within DLX6 in CP1 NSDTRs. The LINE-1 insertion is predicted to insert a premature stop codon within the homeodomain of DLX6. This prompted the sequencing of DLX5 and DLX6 in a human cohort with CP, where a missense mutation within the highly conserved DLX5 homeobox of a patient with PRS was identified. This suggests the involvement of DLX5 in the development of PRS. These results demonstrate the power of the canine animal model as a genetically tractable approach to understanding naturally occurring craniofacial birth defects in humans. PMID:24699068

    Full text: Each one of the 1660 stations of the Surface Detector of the Pierre Auger Observatory is powered by a 100W stand-alone photovoltaic (PV) system composed of a solar panel and two batteries in series on a 24 V setup. Each station continuously stores information by use of a data logger and a radio link. Data is recorded and transmitted roughly every 6 minutes to the Central Data Acquisition Building. In addition to cosmic ray related data, PV performance parameters are also monitored. As a consequence, Auger constitutes an interesting setup for PV stand-alone systems research. In this work, we present the control processes used to ensure optimal performance of the solar power system in the Auger Observatory and propose an upgrade to ensure a better system performance. Most of the work is centered on the batteries, which are the most sensitive elements of the power chain. The batteries are of the Valve Regulated Lead-Acid (VRLA) type, manufactured by Moura-Brazil. A dedicated system has been designed and built in order to qualify the batteries before installation in the field. During regular operation, the monitoring data are exhaustively analyzed in order to detect failures. A set of analysis tools has been developed, both for anomalies detection and for lifetime predictions. From the reported analysis, it has been possible to identify some aspects of the adopted PV system that may be improved, mainly on the batteries voltage unbalance, which rises on charging two batteries in series on a 24V setup. We show that the same behavior is observed in laboratory tests. In order to reduce battery failures, we proposed and tested the detector electronics performance when working with batteries in parallel on a 12V setup. The main changes on the solar power system of the detector are the connections of the solar panel and batteries (from 24V to 12V), the replacement of the charge controller and the introduction a low power DC-DC converter.

    Abstract. This study analyzed the role of ants as anti-herbivore agents in Coffee (Coffea canephora Pierre and Pigeon Pea [Cajanus cajans (L. Millsp] plants in agroecosystem under organic management. In these plants we used artificial eggs and sugar solution in experiments that simulated the presence of herbivore insects. Coffee plants did not possess any natural attractive that could intensify foraging activity of ants, but pigeon pea plants were infested by treehoppers which attracted ants. Activity of ants was surveyed after sugar solution application and artificial eggs removal was measured 24 and 48 h after start of the experiments. Sugar solution sprinkled on plants foliage increased significantly the activity of ants on coffee and pigeon pea plants. The removal of artificial eggs was significantly greater in branch with ants than without ants for pigeon pea plants. The sugar solution addiction resulted in greater artificial eggs removal in pigeon pea plants, but not in coffee plants. The treatment with sugar solution and presence of treehoppers had similar effects on the activity of ants on the plants. This study showed that the application of sugar solution can be used to increase activity of ants on plants as well as the potential of ants as anti-herbivore agents can be evaluated in experiments that simulate the presence of insects on the plants.

    Lumped hydrological models are useful and convenient tools for research, engineering and educational purposes. They propose catchment-scale representations of the precipitation-discharge relationship. Thanks to their limited data requirements, they can be easily implemented and run. With such models, it is possible to simulate a number of hydrological key processes over the catchment with limited structural and parametric complexity, typically evapotranspiration, runoff, underground losses, etc. The Hydrology Group at Irstea (Antony) has been developing a suite of rainfall-runoff models over the past 30 years with the main objectives of designing models as efficient as possible in terms of streamflow simulation, applicable to a wide range of catchments and having low data requirements. This resulted in a suite of models running at different time steps (from hourly to annual) applicable for various issues including water balance estimation, forecasting, simulation of impacts and scenario testing. Recently, Irstea has developed an easy-to-use R-package (R Core Team, 2015), called airGR, to make these models widely available. It includes: - the water balance annual GR1A (Mouehli et al., 2006), - the monthly GR2M (Mouehli, 2003) models, - three versions of the daily model, namely GR4J (Perrin et al., 2003), GR5J (Le Moine, 2008) and GR6J (Pushpalatha et al., 2011), - the hourly GR4H model (Mathevet, 2005), - a degree-day snow module CemaNeige (Valéry et al., 2014). The airGR package has been designed to facilitate the use by non-expert users and allow the addition of evaluation criteria, models or calibration algorithms selected by the end-user. Each model core is coded in FORTRAN to ensure low computational time. The other package functions (i.e. mainly the calibration algorithm and the efficiency criteria) are coded in R. The package is already used for educational purposes. The presentation will detail the main functionalities of the package and present a case

  1. Variability in a three-generation family with Pierre Robin sequence, acampomelic campomelic dysplasia, and intellectual disability due to a novel ∼1 Mb deletion upstream of SOX9, and including KCNJ2 and KCNJ16.

    Campomelic dysplasia and acampomelic campomelic dysplasia (ACD) are allelic disorders due to heterozygous mutations in or around SOX9. Translocations and deletions involving the SOX9 5' regulatory region are rare causes of these disorders, as well as Pierre Robin sequence (PRS) and 46,XY gonadal dysgenesis. Genotype-phenotype correlations are not straightforward due to the complex epigenetic regulation of SOX9 expression during development. We report a three-generation pedigree with a novel ∼1 Mb deletion upstream of SOX9 and including KCNJ2 and KCNJ16, and ascertained for dominant transmission of PRS. Further characterization of the family identified subtle appendicular anomalies and a variable constellation of axial skeletal features evocative of ACD in several members. Affected males showed learning disability. The identified deletion was smaller than all other chromosome rearrangements associated with ACD. Comparison with other reported translocations and deletions involving this region allowed further refining of genotype-phenotype correlations and an update of the smallest regions of overlap associated with the different phenotypes. Intrafamilial variability in this pedigree suggests a phenotypic continuity between ACD and PRS in patients carrying mutations in the SOX9 5' regulatory region. © 2015 Wiley Periodicals, Inc.

Como filho do penúltimo amusnaw (sábio; bardo de sua tribo, Mammeri estava posicionado de maneira única para situar esse mestre das palavras que atuou na função tradicional de mediador e transportador do conhecimento e manteve-se como a encarnação viva da tamusni (a filosofia prática da excelência berbere, em relação com o marabuto (depositário das sagradas escrituras do Corão e com os camponeses (que compõem seu público principal. Torná-se amusnaw graças a uma eleição e isso requer um duplo aprendizado: primeiro, por osmose em um meio saturado de comércio e disputas verbais (no treinamento de guerra, na assembléia da vila, nos mercados e nas peregrinações e, depois, por meio de um treinamento explícito com um poeta-mestre que orienta uma série de exercícios e provas. Esse processo requer não apenas o domínio de uma variedade de técnicas verbais e de um cânone oratório, mas também implica absorver e encarnar a sabedoria. Jogando com a multidimensionalidade da linguagem, adaptando-a com flexibilidade diante das especificidades de cada situação e público, o bardo cabila era continuamente testado e suas habilidades culturais infinitamente refinadas, até o ponto em que ele não apenas dominasse as regras do ofício, mas também jogasse com elas, trangredindo-as no espírito da tradição a fim de inventar novas figuras retóricas e extrair o máximo de "rendimento" da linguagem. A tamusni emerge assim não apenas como um corpo de conhecimento inerte, desligado da vida e transmitido por si mesmo, mas como uma "ciência prática", constantemente revivida pela e para a prática. O poeta é o porta-voz do grupo que, por meio de seu discernimento cultural e uso técnico da linguagem, aperfeiçoa os valores espec

  5. Evaluation of subsidence hazard in mantled karst setting: a case study from Val d'Orléans (France)

    2015-04-01

    Soil subsidence/collapse is a major geohazard occurring in karst region. It occurs as suffosion or dropout sinkholes developing in the soft cover. Less frequently it corresponds to a breakdown of karst void ceiling (i.e., collapse sinkhole). This hazard can cause significant engineering challenges. Therefore decision-makers require the elaboration of methodologies for reliable predictions of such hazards (e.g., karst subsidence susceptibility and hazards maps, early-warning monitoring systems). A methodological framework was developed to evaluate relevant conditioning factors favouring subsidence (Perrin et al. submitted) and then to combine these factors to produce karst subsidence susceptibility maps. This approach was applied to a mantled karst area south of Paris (Val d'Orléans). Results show the significant roles of the overburden lithology (presence/absence of low-permeability layer) and of the karst aquifer piezometric surface position within the overburden. In parallel, an experimental site has been setup to improve the understanding of key processes leading to subsidence/collapse and includes piezometers for measurements of water levels and physico-chemical parameters in both the alluvial and karst aquifers as well as surface deformation monitoring. Results should help in designing monitoring systems to anticipate occurrence of subsidence/collapse. Perrin J., Cartannaz C., Noury G., Vanoudheusden E. 2015.

    Science.gov (United States)

    Gosselin, Gabriel

    Wetlands fill many important ecological functions and contribute to the biodiversity of fauna and flora. Although there is a growing recognition of the importance to protect these areas, it remains that their integrity is still threatened by the pressure of human activities. The inventory and the systematic monitoring of wetlands are a necessity and remote sensing is the only realistic way to achieve this goal. The primary objective of this thesis is to contribute and improve the wetland characterization using satellite polarimetric data acquired in L (ALOS-PALSAR) and C (RADARSAT-2) band. This thesis is based on two hypotheses (Ch. 1). The first hypothesis stipulate that classes of plant physiognomies, based on plant structure, are more appropriate than classes of plant species because they are best adapted to the information content of polarimetric radar data. The second hypothesis states that polarimetric decomposition algorithms allow an optimal extraction of polarimetric information compared to a multi-polarized approach based on the HH, HV and VV channels (Ch. 3). In particular, the contribution of the incoherent Touzi decomposition for the inventory and monitoring of wetlands is examined in detail. This decomposition allows the characterization of the scattering type, its phase, orientation, symmetry, degree of polarization and the backscattered power of a target with a series of parameters extracted from an analysis of the coherency matrix eigenvectors and eigenvalues. The lake Saint-Pierre region was chosen as the study site because of the great diversity of its wetlands that are covering more than 20 000 ha. One of the challenges posed by this thesis is that there is neither a standard system enumerating all the possible physiognomic classes nor an accurate description of their characteristics and dimensions. Special attention was given to the creation of these classes by combining several data sources and more than 50 plant species were grouped into nine

The corpus encompasses the bestiaries comprised by Philippe de Thaon, Gervaise, Guillaume de Normandy, Pierre de Beauvais, Richard de Fournival and pseudo-Pierre de Beauveis, which belong to the tradition of the Physiologoi, as well as other encyclopedic and other works which contain the bookish zoological and geographic knowledge of the middle ages: Mappemonde by Pierre de Beauvais, The letter of presbyter John, and the Mappemonde by Gossouin de Metz. In this corpus where the description of the animals comes mainly from the same written sources (from antiquity and late antiquity and the Bible, we consider how this nonexistent animal is described and to what extent a symbolic interpretation is present.
